System Integration Module (SIM)
7.1 Introduction
This section describes the system integration module (SIM), which supports up to 32 external and/or
internal interrupts. Together with the central processor unit (CPU), the SIM controls all MCU activities. A
block diagram of the SIM is shown in
registers. The SIM is a system state controller that coordinates CPU and exception timing. The SIM is
responsible for:
