Note 1: The blank areas are reserved and cannot be used by users.
Note 2: Bits CM20, CM21, and CM27 do not change at oscillation stop detection reset.
Note 3: This register does not change at software reset, watchdog timer reset and oscillation stop detection reset.
Note 4: This registe can not use for T-ver. and V-ver.
X : Undefined
4. Special Function Registers (SFRs)
SFRs (Special Function Registers) are the control registers of peripheral functions. Table 4.1 to 4.11 list the
