A power-on event will generate an internal POR pulse
when a V

nominally 1.85V. The device supply voltage character-
istics must meet specified starting voltage and rise rate
requirements. The POR pulse will reset a POR timer
and place the device in the Reset state. The POR also
selects the device clock source identified by the oscil-
lator configuration fuses.

Different registers are affected in different ways by var-
ious Reset conditions. Most registers are not affected
by a WDT wake-up, since this is viewed as the resump-
tion of normal operation. Status bits from the RCON
register are set or cleared differently in different Reset
situations, as indicated in Table 21-5. These bits are
used in software to determine the nature of the Reset.
A block diagram of the on-chip Reset circuit is shown in
Figure 21-2.
A MCLR noise filter is provided in the MCLR Reset
path. The filter detects and ignores small pulses.
Internally generated Resets do not drive MCLR pin low.
The POR circuit inserts a small delay, T
nominally 10 s and ensures that the device bias cir-
cuits are stable. Furthermore, a user selected power-
up time-out (T
is based on device Configuration bits and can be 0 ms
(no delay), 4 ms, 16 ms or 64 ms. The total delay is at

the Reset vector.
