Notes:
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: 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 after hardware reset. Refer to the explanation of each register for details.
