NOTES:
1. The blank spaces are reserved. No access is allowed.
2. Bits CM27, CM21, and CM20 do not change at oscillation stop detection reset.
3. The VCR1 and VCR2 registers do not change at software reset, watchdog timer reset, and oscillation stop detection reset.
4. Registers VCR1, VCR2, and D4INT cannot be used in M16C/26T.
