10.7
The TO, PD and (GPWUF/RBWUF) bits in the STATUS
register can be tested to determine if a Reset condition
has been caused by a power-up condition, a MCLR or
Watchdog Timer (WDT) Reset.
TABLE 10-8:
10.8
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 PIC12F510/16F506 devices when a brown-
out occurs, external brown-out protection circuits may
be built, as shown in Figure 10-12 and Figure 10-13.

This brown-out protection circuit employs
Microchip Technology’s MCP809 microcon-
troller supervisor. There are 7 different trip
