NOTES:
1. The blank regions are reserved. Do not access locations in these regions.
2. (N, D version) Software reset, watchdog timer reset, voltage monitor 1 reset, or voltage monitor 2 reset do not affect this register.
(J, K version) Software reset, watchdog timer reset, or voltage monitor 2 reset do not affect this register.
3. The LVD0ON bit in the OFS register is set to 1 and hardware reset.
4. Power-on reset, voltage monitor 0 reset or the LVD0ON bit in the OFS register is set to 0, and hardware reset.
5. (N, D version) Software reset, watchdog timer reset, voltage monitor 1 reset, or voltage monitor 2 reset do not affect b2 and b3.
(J, K version) Software reset, watchdog timer reset, or voltage monitor 2 reset do not affect b2 and b3.
6. (N, D version) Software reset, watchdog timer reset, voltage monitor 1 reset, or voltage monitor 2 reset do not affect this register.
(J, K version) These regions are reserved. Do not access locations in these regions.
7. The LVD1ON bit in the OFS register is set to 1 and hardware reset.
8. Power-on reset, voltage monitor 1 reset, or the LVD1ON bit in the OFS register is set to 0 and hardware reset.
