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 V
CC1
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
