ITCN After Reset

After reset, all of the ITCN registers are in their default states. This means all interrupts are disabled,

except the core IRQs with fixed priorities:

•

Illegal Instruction

•

SW Interrupt 3

•

HW Stack Overflow

•

Misaligned Long Word Access

•

SW Interrupt 2

•

SW Interrupt 1

•

SW Interrupt 0

•

SW Interrupt LP

These interrupts are enabled at their fixed priority levels.

Part 6 System Integration Module (SIM)

6.1 Introduction

The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls

distribution of resets and clocks and provides a number of control features. The System Integration Module

is responsible for the following functions:

•

Reset sequencing

•

Clock control & distribution

•

Stop/Wait control

•

System status registers

•

Registers for software access to the JTAG ID of the chip

•

Test registers

•

Power control

•

I/O pad multiplexing

These are discussed in more detail in the sections that follow.
