Header Setup and Operation - AC244027

This Processor Extension Pak provides extra debugging capability not available on

PIC16LF727 production devices:

• 3 Address / Data breakpoints (1 Address only breakpoint on production devices)

• Data capture (Real Time Data Streaming)

• No user Flash resources needed for debugging

• No user RAM resources needed for debugging

• No user pins required

This header has jumpers available for MCLR pull-up and power LED control.

Test points are available on this header to check the following:

Header Limitations

See the “Limitations” section in your debug tool online Help file for details.

Header Dimensions

The figures below list the dimensions for the debug headers. Dimensions are design

values in inches.

If the length and/or width of the debug header is too large a footprint for the target

board, consider using stand-offs, transition sockets or other extenders in the header

connection socket to raise the header above the target.

Jumper Setting Function

J2 Open

Disable weak ICE MCLR

pull-up resistor.

Short

Enable weak ICE MCLR

pull-up resistor. This option

keeps the target program running even after the tool has

been disconnected from the header, i.e., the pin will not

float high.

Open Disable power LED indicator. This option saves power.

Short

Enable power LED indicator.
