20.3.1
A power-on event will generate an internal POR pulse
when a V
at the POR circuit threshold voltage (V
nominally
characteristics 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 oscillator 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 20-5. 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 20-2.
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 μs and ensures that the device bias
circuits are stable. Furthermore, a user selected
power-up time-out (T
parameter 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 device power-up, T
these delays have expired, SYSRST will be negated on
the next leading edge of the Q1 clock and the PC will
jump to the Reset vector.
The timing for the SYSRST signal is shown in
Figure 20-3 through Figure 20-5.
