The TO, PD, GPWUF and CWUF bits in the Status
register can be tested to determine if a Reset condition
has been caused by a Power-up condition, a MCLR,
Watchdog Timer (WDT) Reset, wake-up on comparator
change or wake-up on pin change.
TABLE 9-5:
9.8
A Brown-out is a condition where device power (V
dips below its minimum value, but not to zero, and then
recovers. The device should be reset in the event of a
Brown-out.
To reset PIC10F200/202/204/206 devices when a
Brown-out occurs, external Brown-out protection
circuits may be built, as shown in Figure 9-7 and
Figure 9-8.

Reset on Brown-out
DD
The TO, PD, GPWUF and CWUF bits maintain their status (u) until a Reset occurs. A low-pulse on the
MCLR input does not change the TO, PD, GPWUF or CWUF status bits.
This circuit will activate Reset when V
below Vz + 0.7V (where Vz = Zener voltage).
Pin must be confirmed as MCLR.
