1.4.2 In-Circuit Programming
J3 and J7 contain all the signals for the MC68HC908JB8 to enter monitor mode for In-Circuit
Programming. The ICP requires J3 and J7 to be connected with a cable to the ICP adaptor board, which
is plugged-into the M68HC08 Serial Programmer (M68SPGRM08) (see
Figure 1-6). Running the
MCUScribe software on the PC allows erase, programming and verification of the firmware in the
MC68HC908JB8. The communication baud rate is determined by the jumper setting of J3 of the ICP
adaptor board. Connect pins 1 and 2 of J3 for 9600bps and pins 2 and 3 for 19200bps.
