Unimplemented: Read as ‘0’
OSCF: INTOSC Oscillator Frequency bit
1 = 4 MHz typical
0 = 48 kHz typical
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)

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
cleared, 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
