Chapter 3 Module Mapping Control (MMCV4) Block Description
3.3.2.2
Read: Anytime
Write: Once in normal and emulation modes and anytime in special modes
This register initializes the position of the internal registers within the on-chip system memory map. The
registers occupy either a 1K byte or 2K byte space and can be mapped to any 2K byte space within the first
32K bytes of the system’s address space.

Internal Register Map Position — These four bits in combination with the leading zero supplied by bit 7 of
INITRG determine the upper five bits of the base address for the system’s internal registers (i.e., the minimum
base address is 0x0000 and the maximum is 0x7FFF).
