MCM Introduction

The Miscellaneous Control Module implements a number of system level features, including the

following:

•

Program-visible information on the device configuration and revision.

•

Software watchdog timer (SWT) with programmable system reset or interrupt response which runs

on a separate, asynchronous clock. The SWT also supports a windowed time period, requiring the

writing of the watchdog key within a specified time window. The source for the SWT clock is

controlled by the Clock and Reset Generator.

•

Wakeup control for entering and exiting sleep modes, including an enable and an interrupt priority

mask.

•

Access address information for faulted memory accesses. When a bus abort occurs in the system,

the exact cause of the abort can be determined by reading the Core Data Fault Recovery Registers

in the MCM.

•

Address map for the crossbar switch (AXBS), which is used to steer access to the Crossbar slave

ports in order to provide remapping operations. Following Reset, the contents of the AAMR

configured by the application code in order to remap the Flash, External bus and RAM between

AXBS Slave Port 0 and Port 1. Please refer to Chapter 9, “Device Memory Map” for further

details.

Core Fault Data Register. This 32-bit register contains the data associated with the faulting access of the

last AMBA-AHB write access. The register contains the data value taken directly from the device write

data bus.
