3 Low-Power System Integration Module
The low-power system integration module (SIML) consists of five functional blocks that control system
startup, initialization, configuration, and the external bus.
Figure 4
shows the SIML block diagram.
Figure 4 SIML Block Diagram
3.1 Overview
The system configuration block controls MCU configuration and operating mode.
The clock synthesizer generates clock signals used by the SIML, other IMB modules, and external de-
vices. In addition, a periodic interrupt generator supports execution of time-critical control routines.
The system protection block provides bus and software watchdog monitors.
The chip-select block provides eleven general-purpose chip-select signals and a boot ROM chip-select
signal. Both general-purpose and boot ROM chip-select signals have associated base address regis-
ters and option registers.
The external bus interface handles the transfer of information between IMB modules and external ad-
dress space.
The system test block incorporates hardware necessary for testing the MCU. It is used to perform fac-
tory tests, and its use in normal applications is not supported.
Table 7
address space return zeros when read. The “Access” column indicates which registers are accessible
only at the supervisor privilege level and which can be assigned to either the supervisor or user privilege
level, according to the value of the SUPV bit in the SIMLCR.
