System Integration Module (SIM)
Introduction
MC68HC08AZ60 — Rev 1.0
84
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
SIM input/output (I/O) registers. The SIM is a system state controller that
coordinates CPU and exception timing. The SIM is responsible for:
