This section describes the system integration module (SIM), which
supports up to 24 external and/or internal interrupts. Together with the
CPU, the SIM controls all MCU activities. A block diagram of the SIM is
shown in
The SIM is a system state controller that coordinates CPU and exception
timing. The SIM is responsible for:
•
•
•
•
•
Bus clock generation and control for CPU and peripherals
– Stop/wait/reset/break entry and recovery
– 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
