POWER CONTROL REGISTER (PCON: 8Eh)
Unimplemented: Read as '0'
WDTON: WDT Software Enable bit
If WDTE bit (Configuration Word <3>) = 1:
This bit is not writable, always reads ‘1’
If WDTE bit (Configuration Word <3>) = 0:
1 = WDT is enabled
0 = WDT is disabled and cleared
OSCF: Oscillator Speed bit (pending on new internal oscillator decision)
INTRC mode:
1 = 4 MHz typical
0 = 37 kHz typical
All other oscillator modes:
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
1 = No Brown-out Reset occurred
0 = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
