Chapter 3 Memory Mapping Control (S12XMMCV4)
3.4.2.5
Two bits in the MMCCTL1 register (ROMHM, RAMHM) configure the mapping of the local address
(0x4000-0x7FFF) in the global memory map.
ROMHM, RAMHM are write once in normal and emulation modes and anytime in special modes.
Three areas are identified (See
Table 3-19
consideration the different configurations of ROMHM and RAMHM.
