5.2 System Configuration
5.2.1 Module Mapping
5-2
The SIM configuration register (SIMCR) governs several aspects of system operation.
The following paragraphs describe those configuration options controlled by SIMCR.
Control registers for all the modules in the microcontroller are mapped into a 4-Kbyte
block. The state of the module mapping (MM) bit in the SIM configuration register
(SIMCR) determines where the control register block is located in the system memory
map. When MM = 0, register addresses range from $7FF000 to $7FFFFF; when MM
= 1, register addresses range from $FFF000 to $FFFFFF.
In M68HC16 Z-series MCUs, ADDR[23:20] follow the logic state of ADDR19 unless
externally driven. MM corresponds to IMB ADDR23. If MM is cleared, the SIM maps
IMB modules into address space $7FF000 – $7FFFFF, which is inaccessible to the
CPU16. Modules remain inaccessible until reset occurs. The reset state of MM is one,
but the bit can be written once. Initialization software should make certain MM remains
set.
