Note 1: The blank areas are reserved and cannot be used by users.
Note 2: The PM00 and PM01 bits do not change at software reset, watchdog timer reset and oscillation stop detection reset.
Note 3: The CM20, CM21, and CM27 bits do not change at oscillation stop detection reset.
Note 4: The WDC5 bit is “0” (cold start) immediately after power-on. It can only be set to “1” in a program. It is set to “0” when the input voltage
at the VCC1 pin drops to Vdet2 or less while the VC25 bit in the VCR2 register is set to “1” (RAM retention limit detection circuit enable
Note 5: This register does not change at software reset, watchdog timer reset and oscillation stop detection reset.
X : Nothing is mapped to this bit
