+===== ICSP (In Circuit Serial Programming) =====
-In Circuit Serial Programming is a means whereby microprocessors (PICs and other types), may be programmed while mounted in the circuit they are intended to control. There are no standard physical designs/pinouts used for in-circuit programming. Many MERG modules using PIC microprocessors are provided with an ICSP connector with a pinout for the popular PICKIT programmer.\\

+ICSP is a means whereby embedded microprocessors are 'programmed' (having their machine code loaded) while mounted in the circuit they are intended to control.
+There are no standard physical designs/pinouts used for ICSP. \\
+Generally MERG modules, with PIC microprocessors, are provided with a 6 way (1 pin omitted) ICSP connector used with a 'twist' cable to a Microchip PICKIT programmer.
+[[:helpsystem:pickit2cbus|MERG PIC ICSP cable pinout shown here.]]\\
+Arduino modules use a USB connection.\\
+AVR ATMEGA chips use a 6 pin connector based on SPI bus. (Optional on Arduino AVR modules)\\
+Atmel SAMD chips have a OneWire ICSP (signal/0v/power).
