+ ################### CRITICAL PROJECT CONSTRAINTS ########################
+ ############################################################################
+
+ ISSP programming can only occur within a temperature range of 5C to 50C.
+ - This project is written without temperature compensation and using
+ programming pulse-widths that match those used by programmers such as the
+ Mini-Prog and the ISSP Programmer.
+ This means that the die temperature of the PSoC device cannot be outside
+ of the above temperature range.
+ If a wider temperature range is required, contact your Cypress Semi-
+ conductor FAE or sales person for assistance.
+
+ The project can be configured to program devices at 5V or at 3.3V.
+ - Initialization of the device is different for different voltages. The
+ initialization is hardcoded and can only be set for one voltage range.
+ The supported voltages ranges are 3.3V (3.0V to 3.6V) and 5V (4.75V to
+ 5.25V). See the device datasheet for more details. If varying voltage
+ ranges must be supported, contact your Cypress Semiconductor FAE or sales
+ person for assistance.
+ - ISSP programming for the 2.7V range (2.7V to 3.0V) is not supported.
+
+ This program does not support programming all PSoC Devices
+ - It does not support obsoleted PSoC devices. A list of devices that are
+ not supported is shown here:
+ CY8C22x13 - not supported
+ CY8C24x23 - not supported (CY8C24x23A is supported)
+ CY8C25x43 - not supported
+ CY8C26x43 - not supported
+ - It does not suport devices that have not been released for sale at the
+ time this version was created. If you need to ISSP program a newly released
+ device, please contact Cypress Semiconductor Applications, your FAE or
+ sales person for assistance.
+ The CY8C20x23 devices are not supported at the time of this release.

+// PROJECT HISTORY
+// date revision author description
+// -------- -------- ------ -----------------------------------------------
+// 7/23/08 3.04 ptj 1. CPU clock speed set to to 12MHz (default) after
+// TSYNC is disabled. Previously, it was being set
+// to 3MHz on accident. This affects the following
+// mnemonics:
+// ID_SETUP_1,
+// VERIFY_SETUP,
+// ERASE,
+// SECURE,
+// CHECKSUM_SETUP,
+// PROGRAM_AND_VERIFY,
+// ID_SETUP_2,
+// SYNC_DISABLE
+//
+// 6/06/08 3.03 ptj 1. The Verify_Setup section can tell when flash
+// is fully protected. bTargetStatus[0] shows a
+// 01h when flash is "W" Full Protection
+// 7/23/08 2. READ-ID-WORD updated to read Revision ID from
+// Accumulator A and X, registers T,F0h and T,F3h
+//
+// 5/30/08 3.02 ptj 1. All vectors work.
+// 2. Main function will execute the
+// following programming sequence:
+// . id setup 1
+// . id setup 2
+// . erase
+// . program and verify
+// . verify (although not necessary)
+// . secure flash
+// . read security
+// . checksum
+//
+// 05/28/08 3.01 ptj TEST CODE - NOT COMPLETE
+// 1. The sequence surrounding PROGRAM-AND-VERIFY was
+// improved and works according to spec.
+// 2. The sequence surroudning VERIFY-SETUP was devel-
+// oped and improved.
+// 3. TSYNC Enable is used to in a limited way
+// 4. Working Vectors: ID-SETUP-1, ID-SETUP-2, ERASE,
+// PROGRAM-AND-VERIFY, SECURE, VERIFY-SETUP,
+// CHECKSUM-SETUP
+// 5. Un-tested Vectors: READ-SECURITY
+//
+// 05/23/08 3.00 ptj TEST CODE - NOT COMPLETE
+// 1. This code is a test platform for the development
+// of the Krypton (cy8c20x66) Programming Sequence.
+// See 001-15870 rev *A. This code works on "rev B"
+// silicon.
+// 2. Host is Hydra 29000, Target is Krypton "rev B"
+// 3. Added Krypton device support
+// 4. TYSNC Enable/Disable is not used.
+// 5. Working Vectors: ID-SETUP-1, ID-SETUP-2, ERASE,
+// PROGRAM-AND-VERIFY, SECURE
+// 6. Non-working Vectors: CHECKSUM-SETUP
+// 7. Un-tested Vectors: READ-SECURITY, VERIFY-SETUP
+// 8. Other minor (non-SROM) vectors not listed.
+//
+// 09/23/07 2.11 dkn 1. Added searchable comments for the HSSP app note.
+// 2. Added new device vectors.
+// 3. Verified write and erase pulsewidths.
+// 4. Modified some functions for easier porting to
+// other processors.
+//
+// 09/23/06 2.10 mwl 1. Added #define SECURITY_BYTES_PER_BANK to
+// file issp_defs.h. Modified function
+// fSecureTargetFlashMain() in issp_routines.c
+// to use new #define. Modified function
+// fLoadSecurityData() in issp_driver_routines.c
+// to accept a bank number. Modified the secure
+// data loop in main.c to program multiple banks.
+//
+// 2. Created function fAccTargetBankChecksum to
+// read and add the target bank checksum to the
+// referenced accumulator. This allows the
+// checksum loop in main.c to function at the
+// same level of abstraction as the other
+// programming steps. Accordingly, modified the
+// checksum loop in main.c. Deleted previous
+// function fVerifyTargetChecksum().
+//
+// 09/08/06 2.00 mwl 1. Array variable abTargetDataOUT was not
+// getting intialized anywhere and compiled as a
+// one-byte array. Modified issp_driver_routines.c
+// line 44 to initialize with TARGET_DATABUFF_LEN.
+//
+// 2. Function void LoadProgramData(unsigned char
+// bBlockNum) in issp_driver_routines.c had only
+// one parameter bBlockNum but was being called
+// from function main() with two parameters,
+// LoadProgramData(bBankCounter, (unsigned char)
+// iBlockCounter). Modified function
+// LoadProgramData() to accept both parameters,
+// and in turn modified InitTargetTestData() to
+// accept and use both as well.
+//
+// 3. Corrected byte set_bank_number[1]
+// inissp_vectors.h. Was 0xF2, correct value is
+// 0xE2.
+//
+// 4. Corrected the logic to send the SET_BANK_NUM
+// vectors per the AN2026B flow chart.The previous
+// code version was sending once per block, but
+// should have been once per bank. Removed the
+// conditionally-compiled bank setting code blocks
+// from the top of fProgramTargetBlock() and
+// fVerifyTargetBlock() int issp_routines.c and
+// created a conditionally-compiled subroutine in
+// that same file called SetBankNumber(). Two
+// conditionally-compiled calls to SetBankNumber()
+// were added to main.c().
+//
+// 5. Corrected CY8C29x66 NUM_BANKS and
+// BLOCKS_PER_BANK definitions in ISSP_Defs.h.
+// Was 2 and 256 respectively, correct values are
+// 4 and 128.
+//
+// 6. Modified function fVerifyTargetChecksum()
+// in issp_routines.c to read and accumulate multiple
+// banks of checksums as required for targets
+// CY8C24x94 and CY8C29x66. Would have kept same
+// level of abstraction as other multi-bank functions
+// in main.c, but this implementation impacted the
+// code the least.
+//
+// 7. Corrected byte checksum_v[26] of
+// CHECKSUM_SETUP_24_29 in issp_vectors.h. Was 0x02,
+// correct value is 0x04.
+//
+// 06/30/06 1.10 jvy Added support for 24x94 and 29x66 devices.
+// 06/09/06 1.00 jvy Changed CPU Clk to 12MHz (from 24MHz) so the
+// host can run from 3.3V.
+// Simplified init of security data.
+// 06/05/06 0.06 jvy Version #ifdef added to each file to make sure
+// all of the file are from the same revision.
+// Added flags to prevent multiple includes of H
+// files.
+// Changed pre-determined data for demo to be
+// unique for each block.
+// Changed block verify to check all blocks after
+// block programming has been completed.
+// Added SetSCLKHiZ to explicitly set the Clk to
+// HighZ before power cycle acquire.
+// Fixed wrong vectors in setting Security.
+// Fixed wrong vectors in Block program.
+// Added support for pods
+// 06/05/06 0.05 jvy Comments from code review. First copy checked
+// into perforce. Code has been updated enough to
+// compile, by implementing some comments and
+// fixing others.
+// 06/04/06 0.04 jvy made code more efficient in bReceiveByte(), and
+// SendVector() by re-arranging so that local vars
+// could be eliminated.
+// added defines for the delays used in the code.
+// 06/02/06 0.03 jvy added number of Flash block adjustment to
+// programming. added power cycle programming
+// mode support. This is the version initially
+// sent out for peer review.
+// 06/02/06 0.02 jvy added framework for multiple chip support from
+// one source code set using compiler directives.
+// added timeout to high-low trasition detection.
+// added multiple error message to allow tracking
+// of failures.
+// 05/30/06 0.01 jvy initial version,
+// created from DBD's issp_27xxx_v3 program.

+ PSoC In-System Serial Programming (ISSP) Template
+ This PSoC Project is designed to be used as a template for designs that
+ require PSoC ISSP Functions.
+
+ This project is based on the AN2026 series of Application Notes. That app
+ note should be referenced before any modifications to this project are made.
+
+ The subroutines and files were created in such a way as to allow easy cut &
+ paste as needed. There are no customer-specific functions in this project.
+ This demo of the code utilizes a PSoC as the Host.
+
+ Some of the subroutines could be merged, or otherwise reduced, but they have
+ been written as independently as possible so that the specific steps involved
+ within each function can easily be seen. By merging things, some code-space
+ savings could be realized.
+
+ As is, and with all features enabled, the project consumes approximately 3500
+ bytes of code space, and 19-Bytes of RAM (not including stack usage). The
+ Block-Verify requires a 64-Byte buffer for read-back verification. This same
+ buffer could be used to hold the (actual) incoming program data.
+
+ Please refer to the compiler-directives file "directives.h" to see the various
+ features.
+
+ The pin used in this project are assigned as shown below. The HOST pins are
+ arbitrary and any 3 pins could be used (the masks used to control the pins
+ must be changed). The TARGET pins cannot be changed, these are fixed function
+ pins on the PSoC.
+ The PWR pin is used to provide power to the target device if power cycle
+ programming mode is used. The compiler directive RESET_MODE in ISSP_directives.h
+ is used to select the programming mode. This pin could control the enable on
+ a voltage regulator, or could control the gate of a FET that is used to turn
+ the power to the PSoC on.
+ The TP pin is a Test Point pin that can be used signal from the host processor
+ that the program has completed certain tasks. Predefined test points are
+ included that can be used to observe the timing for bulk erasing, block
+ programming and security programming.
+
+ SIGNAL HOST TARGET
+ ---------------------
+ SDATA P1.7 P1.0
+ SCLK P1.6 P1.1
+ XRES P2.0 XRES
+ PWR P2.3 Vdd
+ TP P0.7 n/a
+
+ For test & demonstration, this project generates the program data internally.
+ It does not take-in the data from an external source such as I2C, UART, SPI,
+ etc. However, the program was written in such a way to be portable into such
+ designs. The spirit of this project was to keep it stripped to the minimum
+ functions required to do the ISSP functions only, thereby making a portable
+ framework for integration with other projects.
+
+ The high-level functions have been written in C in order to be portable to
+ other processors. The low-level functions that are processor dependent, such
+ as toggling pins and implementing specific delays, are all found in the file
+ ISSP_Drive_Routines.c. These functions must be converted to equivalent
+ functions for the HOST processor. Care must be taken to meet the timing
+ requirements when converting to a new processor. ISSP timing information can
+ be found in Application Note AN2026. All of the sections of this program
+ that need to be modified for the host processor have "PROCESSOR_SPECIFIC" in
+ the comments. By performing a "Find in files" using "PROCESSOR_SPECIFIC" these
+ sections can easily be identified.
+
+ The variables in this project use Hungarian notation. Hungarian prepends a
+ lower case letter to each variable that identifies the variable type. The
+ prefixes used in this program are defined below:
+ b = byte length variable, signed char and unsigned char
+ i = 2-byte length variable, signed int and unsigned int
+ f = byte length variable used as a flag (TRUE = 0, FALSE != 0)
+ ab = an array of byte length variables
+
+ After this program has been ported to the desired host processor the timing
+ of the signals must be confirmed. The maximum SCLK frequency must be checked
+ as well as the timing of the bulk erase, block write and security write
+ pulses.
+
+ The maximum SCLK frequency for the target device can be found in the device
+ datasheet under AC Programming Specifications with a Symbol of "Fsclk".
+ An oscilloscope should be used to make sure that no half-cycles (the high
+ time or the low time) are shorter than the half-period of the maximum
+ freqency. In other words, if the maximum SCLK frequency is 8MHz, there can be
+ no high or low pulses shorter than 1/(2*8MHz), or 62.5 nsec.
+
+ The test point (TP) functions, enabled by the define USE_TP, provide an output
+ from the host processor that brackets the timing of the internal bulk erase,
+ block write and security write programming pulses. An oscilloscope, along with
+ break points in the PSoC ICE Debugger should be used to verify the timing of
+ the programming. The Application Note, "Host-Sourced Serial Programming"
+ explains how to do these measurements and should be consulted for the expected
+ timing of the erase and program pulses.
