Rewrite the PM1 register after the PRC1 bit in the PRCR register is set to 1 (write enable). 2. To access the two 2K-byte data spaces in data block A and data block B, set the PM10 bit to 1. The PM10 bit is not available in mask version. 3. When the FMR01 bit in the FMR0 register is set to 1 (enables CPU rewrite mode), the PM10 bit is automatically set to 1. 4. Set the PM12 bit to 1 by program. (Writing 0 by program has no effect) 5. When the PM17 bit is set to 1 (wait state), one wait is inserted when accessing the internal RAM or the internal ROM. Set to 0 (b1) Reserved bit Set to 1 Reserved bit Set to 0 (b6-b4) Reserved bit (b3) 0 1 0 00 6. Processor Mode The MCU supports single-chip mode only. Figures 6.1 and 6.2 show the associated registers.
