SECTION 5
SYSTEM INTEGRATION MODULE
This section is an overview of the system integration module (SIM). Refer to the SIM
Reference Manual (SIMRM/AD) for a comprehensive discussion of SIM capabilities.
Refer to D.2 System Integration Module for information concerning the SIM address
map and register structure.
5.1 General
The SIM consists of six functional blocks. Figure 5-1 shows a block diagram of the
SIM.
The system configuration block controls MCU configuration parameters.
The system clock generates clock signals used by the SIM, other IMB modules, and
external devices.
The system protection block provides bus and software watchdog monitors. In addi-
tion, it also provides a periodic interrupt timer to support execution of time-critical con-
trol routines.
The external bus interface handles the transfer of information between IMB modules
and external address space.
The chip-select block provides 12 chip-select signals. Each chip-select signal has an
associated base address register and option register that contain the programmable
characteristics of that chip-select.
The system test block incorporates hardware necessary for testing the MCU. It is used
to perform factory tests, and its use in normal applications is not supported.
