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 purposes in future derivatives. The reset value shown in the table for these bits is 0. 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 power up. The BOF flag is set by the occurrence of a brownout reset/interrupt and upon power up. 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 0000b for all other reset causes if the watchdog is disabled. |
