Power Control (PCON0) Register

The Power Control (PCON0) register contains flag bits

to differentiate between a:

• Power-on Reset (POR)

• Brown-out Reset (BOR)

• Reset Instruction Reset (RI)

•MCLR Reset (RMCLR)

• Watchdog Timer Reset (RWDT)

• Stack Underflow Reset (STKUNF)

• Stack Overflow Reset (STKOVF)

The PCON0 register bits are shown in Register 6-2.

Hardware will change the corresponding register bit

during the Reset process; if the Reset was not caused

by the condition, the bit remains unchanged

(Table 6-4).

Software should reset the bit to the inactive state after

the restart (hardware will not reset the bit).

Software may also set any PCON0 bit to the active

state, so that user code may be tested, but no Reset

action will be generated.

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

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 = Value depends on condition

bit 7

SBOREN:

Software Brown-out Reset Enable bit(1)

If BOREN <1:0> in Configuration Words

 01:

SBOREN is read/write, but has no effect on the BOR.

If BOREN <1:0> in Configuration Words = 01:

=BOR Enabled

=BOR Disabled

bit 6

Reserved. Bit must be maintained as ‘0’.

bit 5-1

Unimplemented:

Read as ‘0’

bit 0

BORRDY:

Brown-out Reset Circuit Ready Status bit

= The Brown-out Reset circuit is active

= The Brown-out Reset circuit is inactive

Note 1:

BOREN<1:0> bits are located in Configuration Words.
