The MCU subsystem consists of the MC68HC908RK2 microcontroller, clock
generation and selection, monitor mode control logic that places and holds the
RKICS in monitor mode, the bus voltage level translation buffers, and
processor operating voltage variable regulator.
The MCU is an MC68HC908RK2 and is available in three different packages:
•
20-pin SOIC (small-outline integrated circuit)
•
20-pin SSOP (small shrink outline package)
•
32-pin QFP (quad flat pack)
The QFP package mounts in a clam-shell socket, while the SOIC and SSOP
mount in open-top sockets. All three sockets are available on the board, though
only one at a time can be used.
The on-board MCU (the test MCU) simulates and debugs the MCU's interface
to its peripherals and to other devices on the target board through a variety of
connections.
