The PIC16F630/676 members have on-chip Brown-out
Detect circuitry. A Configuration bit, BODEN, can
disable (if clear/programmed) or enable (if set) the
Brown-out Detect circuitry. If V

On power-up, the time-out sequence is as follows: first,
PWRT time-out is invoked after POR has expired.
Then, OST is activated. The total time-out will vary
based on oscillator configuration and PWRTE bit
status. For example, in EC mode with PWRTE bit
erased (PWRT disabled), there will be no time-out at
all. Figure 9-7, Figure 9-8 and Figure 9-9 depict time-
out sequences.
Since the time-outs occur from the POR pulse, if MCLR
is kept low long enough, the time-outs will expire. Then
bringing MCLR high will begin execution immediately
(see Figure 9-8). This is useful for testing purposes or
to synchronize more than one PIC16F630/676 device
operating in parallel.
Table 9-6 shows the Reset conditions for some special
registers, while Table 9-7 shows the Reset conditions
for all the registers.

The power CONTROL/STATUS register, PCON
(address 8Eh) has two bits.
Bit 0 is BOD (Brown-out). BOD is unknown on Power-
on Reset. It must then be set by the user and checked
on subsequent Resets to see if BOD = 0, indicating that
a brown-out has occurred. The BOD Status bit is a
“don’t care” and is not necessarily predictable if the
brown-out circuit is disabled (by setting BODEN bit = 0
in the Configuration Word).
Bit 1 is POR (Power-on Reset). It is a ‘0’ on Power-on
Reset and unaffected otherwise. The user must write a
‘1’ to this bit following a Power-on Reset. On a
subsequent Reset, if POR is ‘0’, it will indicate that a
Power-on Reset must have occurred (i.e., V
have gone too low).
