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 WDC5 bit is 0 (cold start) immediately after power-on. It can only be set to 1 by program. The WDC5 bit cannot be used in
M16C/26T.
4. The VCR1 and VCR2 registers do not change at software reset, watchdog timer reset, and oscillation stop detection reset.
5. Registers VCR1, VCR2, and D4INT cannot be used in M16C/26T.
