2.2.2.8
The Power Control (PCON) register contains a flag bit
to allow differentiation between a Power-on Reset
(POR) to an external MCLR Reset or WDT Reset.
Those devices with brown-out detection circuitry con-
tain an additional bit to differentiate a Brown-out Reset
condition from a Power-on Reset condition.
The PCON register also contains the frequency select
bit of the INTRC or ER oscillator.

PCON REGISTER
POWER CONTROL REGISTER (PCON: 8Eh)
Unimplemented: Read as '0'
OSCF: Oscillator Speed bit
INTRC Mode
1 = 4 MHz nominal
0 = 37 kHz nominal
ER Mode
1 = Oscillator frequency depends on the external resistor value on the OSC1 pin.
0 = 37 kHz nominal
All other modes
x = Ignored
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 (See Section 2.2.2.8 Note)
1 = No Brown-out Reset occurred
0 = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)

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 BODEN
bit in the Configuration word).
