Notes:
1. The blank areas are reserved. No access is allowed.
2. Hardware reset, power-on reset, voltage monitor 0 reset, or voltage monitor 2 reset.
3. Software reset, watchdog timer reset, oscillator stop detect reset, and voltage monitor 2 reset do not affect the
following registers or bit: the VW0C register, and bits VW2C2 and VW2C3 in the VW2C register.
4. This is the reset value when the LVDAS bit of the OFS1 address is 1 during hardware reset
5. 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.
6. This is the reset value after hardware reset, power-on reset, or voltage monitor 0 reset
