ICD connector enables communication between the microcontroller and external ICD debugger/programmer from Microchip (ICD2
or ICD3
MikroElektronika
PIC microcontrollers can be programmed either in Low Voltage or High Voltage programmings modes. The PICfl ash programmer uses
solely High Voltage programming mode for its operation. Such mode requires voltage higher than the microcontroller’s power supply
voltage to be brought to the MCLR/Vpp pin in order for the programming process to be performed. The voltage value usually ranges
between 8 and 14V depending on the type of the microcontroller in use.
The Low Voltage programming mode can be enabled/disabled using confi guration bits of the microcontroller. If the Low Voltage programming
mode is enabled, the programming process is initiated by applying a logic one (1) to the PGM pin. Unlike this mode, the High Voltage
programming mode is always enabled and the programming process starts by applying a high voltage to the MCLR/VPP pin.
All the settings that have to do with programming the microcontrollers are automatically performed and no extra work is needed.
However, there is a number of options for additional programming settings provided in the PICfl ash program. It is not recommended
for beginners to change the default settings.
One of the advantages offered by the on-board PIClash programmer is a multiplexer.

disconnects the microcontroller pins used for
programming from the rest of the board and
connects them to the PICfl ash programmer. After
the programming is complete, these pins are
disconnected from the programmer and may be
used as input/output pins.
