[2] The PCON reset value is xxBOF POF - 0000b. 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. [3] 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.
