USER’S MANUAL

D.7 Multichannel Communication Interface Module

The MCCI is used only in the MC68HC16Z4 and the MC68CK16Z4. Table D-37

shows the MCCI address map.

D.7.1 MCCI Module Configuration Register

MMCR bits enable stop mode, establish the privilege level required to access certain

MCCI registers, and determine the arbitration priority of MCCI interrupt requests.
