1. Set the PM0 register after the PRC1 bit in the PRCR register is set to 1 (write enable).
2. Bits PM01 and PM00 maintain values set before reset, even after software reset or watchdog timer reset has performed.
3. When using memory expansion mode or microprocessor mode, first set bits PM02, PM05 and PM04, and PM07 in the PM0

register, and also set bits PM11 and PM10, PM15 and PM14 in the PM1 register. Then, set bits PM01 and PM00.
combination with bits PM11 and PM10 in the PM 1 register. Do not set bits PM05 and PM04 to 11b in microprocessor mode since
the MCU starts up with the separate bus after reset. Refer to the Table “Multiplexed Bus Settings and Chip-Select Areas” in
the Bus chapter.
To output BCLK from P5_3 in memory expansion mode and microprocessor mode, set the PM07 bit to 0, bits CM01 and CM00 in
the CM0 register to “00b” (I/O port P5_3), and bits PM15 and PM14 in the PM1 register to 00b, 10b, or 11b.
