ICSP™ programming allows customers to manufacture
circuit boards with unprogrammed devices. Programming
can be done after the assembly process allowing the
device to be programmed with the most recent firmware
or a custom firmware. Five pins are needed for ICSP™
programming:
• ICSPCLK
• ICSPDAT
• MCLR/V
• V
• V
In Program/Verify mode the program memory, user IDs
and the Configuration Words are programmed through
serial communications. The ICSPDAT pin is a
bidirectional I/O used for transferring the serial data
and the ICSPCLK pin is the clock input. For more

(DS41397).

The device is placed into High-Voltage Programming
Entry mode by holding the ICSPCLK and ICSPDAT
pins low then raising the voltage on MCLR/V
