Processor Mode
1. For setting bits PM01 to PM00 to 01b (memory expansion mode) and bits PM05 to PM04 to 11b
2. In separate bus mode, these pins serve as the address bus.
3.
4. When accessing the area that uses a multiplexed bus, these pins output an undefined value during
(multiplexed bus assigned to the entire CS space), apply “H” to the BYTE pin (external data bus is an
8-bit width). While the CNVSS pin is held “H” (VCC), do not rewrite bits PM05 to PM04 to 11b after
reset. If bits PM05 to PM04 are set to 11b during memory expansion mode, P3_1 to P3_7 and P4_0 to
P4_3 become I/O ports, in which case the accessible area for each CS is 256 bytes.
If the data bus is 8-bit width, make sure the PM02 bit is set to 0 (RD, BHE, WR).
