The Module Mapping Control (MMC) sub-block of the Core performs all
mapping and select operations for the on-chip and external memory
blocks. The MMC also handles mapping functions for the system
peripheral blocks and provides a global peripheral select to be decoded
by the Motorola I.P. Bus when the Core is addressing a portion of the
peripheral register map space. All bus-related data flow and multiplexing
for the Core is handled within the MMC as well. Finally, the MMC also
contains logic to determine the state of system security.
• Registers for mapping of address space for on-chip RAM,
CALRAM, and Flash EEPROM memory blocks and associated
registers
• Memory mapping control and selection based upon address
decode and system operating mode
