System Integration Module (SIM)
This chapter provides detailed operation information regarding the system integration
module (SIM). It describes the SIM programming model, bus arbitration, power
management, and system-protection functions for the MCF5272.
6.1 Features
The SIM, shown in Figure 6-1, provides overall control of the bus and serves as the
interface between the ColdFire core processor complex and the internal peripheral devices.
