Preliminary
Part 6 System Integration Module (SIM)
6.1 Overview
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 generation & distribution
Stop/Wait control
Pullup enables for selected peripherals
System status registers
Registers for software access to the JTAG ID of the chip
Enforcing Flash security
These are discussed in more detial in the sections that follow.
6.2 Features
The SIM has the following features:
Flash security feature prevents unauthorized access to code/data contained in on-chip Flash memory
Power-saving clock gating for peripheral
Three power modes (Run, Wait, Stop) to control power utilization
— Stop mode shuts down the 56800E core, system clock, peripheral clock, and PLL operation
— Stop mode entry can optionally disable PLL and Oscillator (low power vs. fast restart); must be
explicitly done
— Wait mode shuts down 56800E core and unnecessary system clock operation
— Run mode supports full part operation
Controls to enable/disable the 56800E core WAIT and STOP instructions
Calculates base delay for reset extension based upon POR or RESET operations. Reset delay will be 3 x 32
clocks (phased release of reset) for reset, except for POR, which is 221 clock cycles.
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
6.3 Operating Modes
Since the SIM is responsible for distributing clocks and resets across the chip, it must understand the
various chip operating modes and take appropriate action. These are:
