System Integration Module (SIM)
7.2 Introduction
Technical Data
90
This section describes the system integration module (SIM). Together
with the central processor unit (CPU), the SIM controls all
microcontroller unit (MCU) activities. A block diagram of the SIM is
shown in
(I/O) registers.
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
computer operating properly (COP) timeout
Interrupt control:
– Acknowledge timing
– Arbitration control timing
– Vector address generation
CPU enable/disable timing
Modular architecture expandable to 128 interrupt sources
