4. Special Function Register (SFR)
SFR(Special Function Register) is the control register of peripheral functions. Tables 4.1 to 4.6 list the SFR
information.
NOTES:
1. The blank areas are reserved and cannot be accessed by users.
2. The PM00 and PM01 bits do not change at software reset, watchdog timer reset and oscillation stop detection reset.
3. The CM20, CM21, and CM27 bits do not change at oscillation stop detection reset.
4. The WDC5 bit is “0” (cold start) immediately after power-on. I t can only be set to “1” in a program.
5. This register does not change at software reset, watchdog timer reset and oscillation stop detection reset.
6. This register in M16C/62PT cannot be used.
X : Nothing is mapped to this bit
