Emulation of the MC68HC908RK2's RST signal is also limited in that the
signal is not a bidirectional, open-drain signal. It is emulated as either an input
or an output (determined by jumper header W3) when using the target
connectors or as two pins (one input and one output) when using the MON08
cable.
The installation procedure in 2.4 Installing the Hardware describes how to
prepare the M68ICS08RK for use in the modes where the MCU is installed on
the RKICS board.
These modes include:
• Using the M68ICS08RK as an in-circuit simulator/emulator with a target
cable
• Using the M68ICS08RK as a programmer
• Using the M68ICS08RK as a stand-alone system without a target board
If difficulties are experienced when starting the kit using the procedure outlined
in 2.4 Installing the Hardware, follow these steps:
1. In these modes, do not use the MON08 cable to a target system. Use the
MON08 cable connection only when the MCU is on the target system.
Troubleshooting information for the MON08 mode is found in B.5
Troubleshooting MON08 Mode.
2. Disconnect any target cables from the board. These troubleshooting steps
assume that no target system connections are present.
3. Make sure that the MCU is installed correctly. Verify that only one MCU
is installed in either XU1, XU2, or XU3. Insert the MCU with the
orientation notch and pin 1 to the upper left in the respective socket.
4. Make sure the board is getting power:
a. Check the power at the output of the adapter. First disconnect the
RKICS from the power supply, then measure the power at the wall
adapter's output connector to confirm that it produces +5 Vdc. The
