Write to this register after setting the PRC1 bit in the PRCR register to “1” (w rite enable).
Effective w hen the PM01 to PM00 bits are set to “01b” (memory expansion mode) or “11b” (microprocessor mode).
To set the PM01 to PM00 bits are “01b” and the PM05 to PM04 bits are “11b” (multiplexed bus assigned to the entire
