NOTE:
User's Manual

Depending on the connection, the MCU is used in one of three operating modes:
•
In the ICS socket for programming and simple simulation
•
In the socket and connected to the target for emulation
•
On the target for MON08 debug operation
The RKICS has an operation voltage range of +2.0 to +3.3 volts while the host
development system interface is an RS-232 (COM) port. U3 on the ICS
converts 5-volt logic signals to RS-232 levels. ICS U5–U6 translate 5-volt logic
levels to the MCU operating voltage (2.0–3.3 volts).
The tables in this section describe the pin assignments for the connectors on the
M68ICS08RK2 board.
The signal descriptions in the following tables are for quick reference only. The
MC68HC908RK2 User's Manual, MC68HC908RK2/D, contains a complete
description of the MC68HC908RK2 MCU signals.
