Note 1: Write to this register after setting the PRC1 bit in the PRCR register to “1” (write enable).
Note 2: For the mask ROM version, this bit must be set to “0” . For the flash memory version, the PM10 bit also
controls block A by enabling or disabling it. However, the PM10 bit is automatically set to “1” when the FMR0
1 bit in the FMR0 register is “1” (CPU rewrite mode).
Note 3: Effective when the PM01 to PM00 bits are set to “012” (memory expansion mode) or “112” (microprocessor
mode).
Note 4: PM12 bit is set to “1” by writing a “1” in a program. (Writing a “0” has no effect.)
Note 5: When PM17 bit is set to “1” (with wait state), one wait state is inserted when accessing the internal RAM,
internal ROM, or an external area. If the CSiW bit (i = 0 to 3) in the CSR register is “0” (with wait state), the
CSi area is always accessed with one or more wait states regardless of whether the PM17 bit is set or not.
Where the RDY signal is used or multiplex bus is used, set the CSiW bit to “0” (with wait state).
Note 6: The PM13 bit is automatically set to “1” when the FMR01 bit in the FMR0 register is “1” (CPU rewrite mode).
Note 7: The access area is changed by the PM13 bit as listed in the table below.

0 : No wait state
