PCON REGISTER

The Power Control (PCON) register (see Table 19-2)

contains flag bits to differentiate between a:

• Power-on Reset (POR)

• Brown-out Reset (BOR)

• Watchdog Timer Reset (WDT)

• External MCLR Reset

The PCON register also controls the software enable of

the BOR.

The PCON register bits are shown in Register 2-8.

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

q = unchanged
