Mapping of Memory: Miscellaneous
Bits of the Miscellaneous Mapping Contol Register (MISC, at 0x0013) affect location of Flash EEPROM (B32) or ROM (BE32).
- MAPROM (bit 1) maps this memory to
- $8000 to $FFFF if one;
- $0000 to $7FFF if zero.
- ROMON (bit 0) enables (one) or disables (zero) the flash EEPROM or ROM.
If conflicting address specifications are given, the register block takes preference over RAM and EEPROM which have priority over Flash EEPROM / ROM.
Resource mapping is covered in section 5.3 of the M68HC12B Family Data Sheet.
