NOTES:
1. The PM00 and PM01 bits in the PM0 register do not change at software reset, watchdog timer reset and oscillation stop detection reset.
* Effective when memory expansion and microprocessor modes (= Normal-ver.).
2. The CM20, CM21, and CM27 bits in the CM2 register do not change at oscillation stop detection reset.
3. CNVSS pin = H is not available in T/V-ver.. Do not set a value.
4. These registers are not available in T/V-ver.
5. The blank areas are reserved and cannot be accessed by users.
