1.2 Pin Utilization
Five pins are needed for ICSP™ programming. It is
recommended to use the pins listed in Table 1-1. For
PIC18F1XK50 legacy designs refer to Section 4.2.1
“Legacy ICSP Pinout Programming”.

Note 1:
I = Input, O = Output, P = Power
The programming high voltage is internally generated. To activate the Program/Verify mode, high voltage needs to be
applied to MCLR input. Since the MCLR is used for a level source, MCLR does not draw any significant current.
