* SFRs are bit addressable.
# SFRs are modified from or added to the 80C51 SFRs.
1. Unimplemented bits in SFRs are X (unknown) at all times. Ones should not be written to these bits since they may be used for other
2. I/O port values at reset are determined by the PRHI bit in the UCFG1 configuration byte.
3. The PCON reset value is x x BOF POF–0 0 0 0b. The BOF and POF flags are not affected by reset. The POF flag is set by hardware upon
4. The WDCON reset value is xx11 0000b for a Watchdog reset, xx01 0000b for all other reset causes if the watchdog is enabled, and xx00
