System Integration Module (SIM)
7.1 Introduction
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:
