Appendix B. Daughter Board Specifications
This appendix discusses the various specifications and jumper link
configuration settings for those daughter boards that were available at the
time this document was published.
For more current information, refer to the links.txt file in the MPLAB
ICEPIC disk.
Topics covered in this appendix:
These links configure the system emulator chip. For normal operation with the
OSC Module supplied, these links should be left open.
For all PICmicro MCU pins, OSC1 and OSC2 can be input or output. The only
mode where OSC2 in a output is RC mode. Then, the output from OSC2 is
1/4 of the frequency at OCS1.
The function of the PIC16C01 or PIC16C02 is the same as for any PICmicro
MCU with the mode of operation being set by the two links A and B on the
personal daughter board, just above the OSC module.
The ICEPIC Daughter Board is driven from an EXT source (CMOS/TTL
output Oscillator Module) which feeds into OSC1. Therefore, if you connect
the Links to RC mode, you should see the 1/4 frequency on OSC2.
This link connects a weak pull-up resistor (27 kΩ) to the emulator MCLR
input. This link must be connected to enable all functions such as a single
step, animate or when the emulator is halted. It may be removed when
running in real time, thereby truly emulating a reset condition.
