4 / 12 page MPLAB® ICD 2 DS51292L-page 4 © 2005 Microchip Technology Inc. 18-PIN HEADERS For these headers, there are no jumpers/switches. The device with the most program memory is always selected. If PIC16F627A or PIC16F628A devices are selected for MPLAB ICD 2 development in MPLAB IDE, the warning “ICDWarn0020: Invalid target device id” may be received in the build window and as a dialog. The reason is the PIC16F648A-ICD device supports PIC16F648A, PIC16F627A and PIC16F628A, but only reports the device ID for the PIC16F648A. Ignore this warning or disable it under the Warnings tab on the ICD Programming dialog. 20-PIN HEADER – PIC16F639 For the PIC16F639 20-pin header, you will need to connect the jumper J3 as specified below. In addition to being used with MPLAB ICD 2, this header is used with the PCM16YM0 processor module to emulate a PIC16F639 on the MPLAB ICE 2000 in-circuit emulator. Plug the end of the processor module into the header, and then plug the header into the transition socket or directly onto the target board. 20-PIN HEADER – PIC16F785 For the PIC16F785 20-pin header, you will need to connect the jumper J2 to enable the shunt regulator. 20-PIN HEADER – PIC16F690 For the PIC16F690 20-pin header, you will need to set the S1 switches (Figure 2) to enable peripherals and choose devices (Table 3).
