Introduction
The reset logic is used to place the device into a known state. The source of the reset can be
determined by using the device status bits. The reset logic is designed with features that reduce
system cost and increase system reliability.
Devices differentiate between various kinds of reset:
a)
b)
c)
d)
e)
f)
Most registers are unaffected by a reset; their status is unknown on POR and unchanged by all
other resets. The other registers are forced to a “reset state” on Power-on Reset, MCLR, WDT
reset, Brown-out Reset, Parity Error Reset, and on MCLR reset during SLEEP.
The on-chip parity bits that can be used to verify the contents of program memory.
Most registers are not affected by a WDT wake-up, since this is viewed as the resumption of nor-
mal operation. Status bits TO, PD, POR, BOR, and PER are set or cleared differently in different
reset situations as indicated in
of the reset. See
A simplified block diagram of the on-chip reset circuit is shown in
is a superset of reset features. To determine the features that are available on a specific device,
please refer to the device’s Data Sheet.
All new devices will have a noise filter in the MCLR reset path to detect and ignore small pulses.
See
Note:
Power-on Reset (POR)
MCLR reset during normal operation
MCLR reset during SLEEP
WDT reset during normal operation
Brown-out Reset (BOR)
Parity Error Reset (PER)

While the PICmicro™ is in a reset state, the internal phase clock is held at Q1
(beginning of an instruction cycle).

in the
“Electrical Specifications”
for a full description of the reset states of all registers.
Table
3-2. These bits are used in software to determine the nature
section for pulse width specification.
