This section describes the system integration module (SIM). Together
with the CPU, the SIM controls all MCU activities. A block diagram of the
SIM is shown in
input/output (I/O) registers. The SIM is a system state controller that
coordinates CPU and exception timing. The SIM is responsible for:

– Internal clock control
Master reset control, including power-on reset (POR) and COP
timeout
Interrupt control:
– Acknowledge timing
– Arbitration control timing
– Vector address generation
CPU enable/disable timing
Modular architecture expandable to 128 interrupt sources
