4.2.1 Module Mapping
4.2.2 Interrupt Arbitration
MC68332
USER’S MANUAL
Control registers for all the modules in the microcontroller are mapped into a 4-Kbyte
block. The state of the module mapping bit (MM) 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.
Each module that can generate interrupt requests has an interrupt arbitration (IARB)
field. Arbitration between interrupt requests of the same priority is performed by serial
contention between IARB field bit values. Contention must take place whenever an in-
