1.3.4. Reset Memory Map

Clear Reset Map register

Write-only. Writing to the clear reset memory map location causes the system memory map to change from that required after reset, to that required during normal operation.

When the reset memory map has been cleared and the normal memory map is in use, there is no method of resuming the reset memory map, other than undergoing a power on reset condition.A typical system implementation is to map the system ROM to location 0 at reset, but to change the memory map after reset, such that RAM is located at location 0 for normal operation. In a system where such remapping does not occur, writing to this register has no effect.
