Figure 6.1 PM0 Register
Processor Mode Register 0
NOTES:
b7
1. Rewrite this register after setting the PRC1 bit in the PRCR register to 1 (write enabled).
2. Bits PM01 to PM00 do not change at software reset, watchdog timer reset and oscillation stop detection reset.
3. Effective when bits PM01 to PM00 are set to 01b (memory expansion mode) or 11b (microprocessor mode).
4. To set bits PM01 to PM00 are 01b and bits PM05 to PM04 are 11b (multiplexed bus assigned to the entire

CS space), apply an "H" signal to the BYTE pin (external data bus is 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.
