Special Function Registers (SFRs) 4.1 SFRs An SFR is a control register for a peripheral function. Table 4.1 to Table 4.15 list SFR information. Notes: X: Undefined 1. The blank areas are reserved. No access is allowed. 2. Software reset, watchdog timer reset, oscillator stop detect reset, voltage monitor 1 reset, and voltage monitor 2 reset do not affect the following bits and registers: the VCR1 register, the VCR2 register, and bits PM01 and PM00 in the PM0 register. 3. Oscillator stop detect reset does not affect bits CM20, CM21, and CM27. 4. The state of bits in the RSTFR register depends on the reset type. 5. This is the reset value when the LVDAS bit of address OFS1 is 1 during hardware reset. 6. This is the reset value after voltage monitor 0 reset, power-on reset, and when the LVDAS bit of address OFS1 is 0 during hardware reset.
