SECTION 5 SYSTEM INTEGRATION MODULE
●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 addition, it also provides a periodic interrupt timer to support execution of time-critical control 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.
