ICSP Mode

This mode allows you to program via the ICSP port.

Please note that K128, K128-ICSP, and K182 all have high impedance voltage sources for the high voltage program mode. This means that the target circuit must not draw any significant current from the programmer VPP pin. It is only intended as a voltage level for the FLASH PICmicros®, not a current source.

There are 2 VPP voltage sources available on the programming socket. Either one is automatically selected depending on the chip type selected.

When ICSP mode is selected, only VPP1 is used even if VPP2 should be used for the particular chip. Therefore, do not attempt to program chips in the programming socket when ICSP mode is enabled or chip damage may result.

See the construction PDF file in your installation directory for more ICSP connection information. This will have the same name as your kit type - eg. k149.pdf.

Please note that ICSP programming will not work in all cases. Things that may cause problems are...

high capacitive loads on the programming pins

long programming leads

inability of the programmer to control the MCLR pin

inability of the programmer to control the VCC voltage

If any of these or other problems exist, then you may have to isolate the programming pins on the target board.
