+// The Delay() routine, in ISSP_Driver_Routines.c, has a delay of n+3 usec,
+// where n is the value passed to the routine.  This is true for the m8c micro-
+// processor in the PSoC when it is running at a CPU clock of 24MHz.
+//
+// PROCESSOR_SPECIFIC
+// If another processor is used, or if the m8c is running at a slower clock
+// speed, then the delay parameters will be different. This file makes changing
+// the delays simpiler when porting the program to other processors.

+// DELAY_M is the slope of the Delay = Mx + B equation

+// For the above parameters the minimum delay value is 3 (this would result in
+// 0 being passed for a minimum delay. A value less than 3 would actually
