1. Rewrite the PM0 register after the PRC1 bit in the PRCR register is set to "1" (write enable).
2. Processor mode is not changed even if the PM03 bit is set to "1" (software reset).
3. Set the PM01 to PM00 bits to "01
4. When using the 16-bit data bus in the DRAMC, set the PM02 bit to "1".
5. The PM05 to PM04 bits are available in memory expansion mode or microprocessor mode.
6. The PM05 to PM04 bits cannot be set to "11
7. No BCLK is output in single-chip mode even if the PM07 bit is set to "0". When a clock output is
8. When the PM07 bit is set to "0" (BCLK output), set the CM01 and CM00 bits to "00
