Figure 6.2 PM1 Register
Processor Mode Register 1
NOTES:
b7
1. Rewrite this register after setting the PRC1 bit in the PRCR register to 1 (write enabled).
2. For the mask ROM version, this bit is set to 0.
3. Effective when bits PM01 to PM00 are set to 01b (memory expansion mode) or 11b (microprocessor mode).
4. The PM12 bit is set to 1 by writing a 1 in a program. (writing a 0 has no effect.)
5. Be sure to set this bit to 0 except for products with internal ROM area over 192 Kbytes.
6. When the PM17 bit is set to 1 (with wait state), one wait state is inserted when accessing the internal RAM

For the flash memory version, the PM10 bit controls whether block A is enabled or disabled. When the PM10
bit is set to 1, 0F000h to 0FFFFh (block A) can be used as internal ROM area.
In addition, the PM10 bit is automatically set to 1 while the FMR01 bit in the FMR0 register is set to 1 (CPU
rewrite mode).
The PM13 bit is automatically set to 1 while the FMR01 bit in the FMR0 register is set to 1 (CPU rewrite mode).
or internal ROM.
When the PM17 bit is set to 1 and accesses an external area, set the CSiW bit (i = 0 to 3) in the CSR register
to 0 (with wait state).
