Notes:
1. The blank areas are reserved. No access is allowed.
2. Software reset, watchdog timer reset, oscillator stop detect reset, and voltage monitor 2 reset do not affect the
following registers: registers VCR1 and VCR2.
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 the OFS1 address is 1 during hardware reset.
6. This is the reset value after voltage monitor 0 reset, power-on reset, or when the LVDAS bit of the OFS1 address is 0
during hardware reset.
