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:
These are discussed in more detail in the sections that follow.
6.2 Features
The SIM has the following features:

Reset sequencing
Clock control & distribution
Stop/Wait control
Pull-up enables for selected peripherals
System status registers
Registers for software access to the JTAG ID of the chip
Enforcing Flash security
Flash security feature prevents unauthorized access to code/data contained in on-chip flash memory
Power-saving clock gating for peripherals
Three power modes (Run, Wait, Stop) to control power utilization
— Stop mode shuts down the 56800E core, system clock, and peripheral clock
— Stop mode entry can optionally disable PLL and Oscillator (low power vs. fast restart)
— Wait mode shuts down the 56800E core and unnecessary system clock operation
— Run mode supports full part operation
Controls to enable/disable the 56800E core WAIT and STOP instructions
Controls reset sequencing after reset
Software-initiated reset
Four 16-bit registers reset only by a Power-On Reset usable for general-purpose software control
System Control Register
Registers for software access to the JTAG ID of the chip
