TIME-OUT SEQUENCE
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 RC mode with PWRTE bit erased (PWRT
disabled), there will be no time-out at all. Figure 10-8,
Figure 10-9
and
Figure 10-10
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 10-9). This is useful for testing purposes or
to synchronize more than one PICmicro device oper-
ating in parallel.
Table 10-5 shows the reset conditions for some special
registers, while Table 10-6 shows the reset conditions
for all the registers.
10.4.6
POWER CONTROL (PCON)/STATUS
REGISTER
The power control/status register, PCON (address
8Eh) has two bits.
Bit0 is BOR (Brown-out). BOR is unknown on
power-on-reset. It must then be set by the user and
checked on subsequent resets to see if BOR = 0
indicating that 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
setting BODEN bit = 0 in the Configuration word).
Bit1
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 (VDD may have
gone too low).
