Miscellaneous Control Module (MCM)

13.1

Introduction

The Miscellaneous Control Module (MCM), formerly known as the System Control Module (SCM),

provides a myriad of miscellaneous control functions for the device including program-visible information

about configuration and revision levels, a reset status register, a software watchdog timer, wakeup control

for exiting sleep modes, and optional features such as an address map for the device’s crossbar switch,

information on memory errors reported by error-correcting codes and/or generic access error information

for certain processor cores.

13.1.1

Overview

The Miscellaneous Control Module is mapped into the IPS space and supports a number of miscellaneous

control functions for the device.

13.1.2

Features

The MCM includes these features:

•

Program-visible information on the device configuration and revision

•

Reset status register (MRSR)

•

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

on a separate, asynchronous clock

•

Wakeup control for exiting sleep modes

•

Optional address map for device’s crossbar switch (AXBS)

•

Optional registers for capturing information on memory errors if error-correcting codes (ECC) are

implemented

•

Optional registers to specify the generation of single- and double-bit memory data inversions for

test purposes if error-correcting codes are implemented

•

Optional access address information for faulted memory accesses for certain processor core

micro-architectures, e.g. ARM7TDMI-S

•

Non-Maskable Interrupt with programmable polarity.

Memory Map/Register Definition

This section details the programming model for the Miscellaneous Control Module. This is a 128-byte

space mapped to the region serviced by an IPS bus controller.
