Chapter 4 Multiplexed External Bus Interface (MEBIV3)
4.3.2.13
This register location is not used (reserved). All bits in this register return logic 0s when read. Writes to
this register have no effect.
This register is not in the on-chip memory map in expanded and special peripheral modes. Therefore, these
accesses will be echoed externally.
