Pin Utilization

Five pins are needed for ICSP™ programming. The

pins are listed in Table 1-1 and Table 1-2.

Pin Description

RB6

ICSPCLK

I

Clock Input – Schmitt Trigger Input

RB7

ICSPDAT

I/O

Data Input/Output – Schmitt Trigger Input

Program/Verify mode

Program Mode Select/Programming Power Supply

P

Power Supply

P

Ground

Legend:

I = Input, O = Output, P = Power

Note 1:

In the PIC12F/LF1822 and PIC16F/LF182X, 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.
