PIC16F87/88
2.2.2.8
The Power Control (PCON) register contains a flag bit
to allow differentiation between a Power-on Reset
(POR), a Brown-out Reset, an external MCLR Reset
and WDT Reset.
REGISTER 2-8:
DS30487C-page 24
Note:
bit 7-2
bit 1
bit 0
Interrupt flag bits get set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit, or the global
enable bit, GIE (INTCON<7>). User
software should ensure the appropriate
interrupt flag bits are clear prior to
enabling an interrupt.
PCON Register
PCON: POWER CONTROL REGISTER (ADDRESS 8Eh)
bit 7
Unimplemented: Read as ‘0’
POR: Power-on Reset Status bit
1 = No Power-on Reset occurred
0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
BOR: Brown-out Reset Status bit
1 = No Brown-out Reset occurred
0 = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
Legend:
R = Readable bit
-n = Value at POR

W = Writable bit

Note:
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
BOR is unknown on Power-on Reset. It
must then be set by the user and checked
on subsequent Resets to see if BOR is
clear, indicating a brown-out has occurred.
The BOR status bit is a ‘don’t care’ and is
not necessarily predictable if the brown-
out circuit is disabled (by clearing the
BOREN bit in the Configuration Word
register).
