4.2
The Master Clear Reset (MCLR) pin provides a method
for triggering a hard external Reset of the device. A
Reset is generated by holding the pin low. PIC18
extended microcontroller devices have a noise filter in
the MCLR Reset path, which detects and ignores small
pulses.
The MCLR pin is not driven low by any internal Resets,
including the WDT.
4.3
A POR condition is generated on-chip whenever V
rises above a certain threshold. This allows the device
to start in the initialized state when V
operation.
To take advantage of the POR circuitry, tie the MCLR
pin through a resistor (1 kΩ to 10 kΩ) to V
eliminate external RC components usually needed to
create a POR delay.
When the device starts normal operation (i.e., exits the
Reset
(voltage, frequency, temperature, etc.) must be met to
ensure operation. If these conditions are not met, the
device must be held in Reset until the operating
conditions are met.
POR events are captured by the POR bit (RCON<1>).
The state of the bit is set to ‘0’ whenever a Power-on
Reset occurs; it does not change for any other Reset
event. POR is not reset to ‘1’ by any hardware event.
To capture multiple events, the user manually resets
the bit to ‘1’ in software following any POR.

“F” devices incorporate two types of BOR circuits: one
which monitors V
Only one BOR circuit can be active at a time. When in
normal Run mode, Idle or normal Sleep modes, the
BOR circuit that monitors V

During Deep Sleep operation, the on-chip core voltage
regulator is disabled and V
ground levels. If the Deep Sleep BOR circuit is enabled
by the DSBOREN Configuration bit (CONFIG3L<2> = 1),
it will monitor V
threshold, the device will be held in a Reset state
similar to POR. All registers will be set back to their POR
Reset values and the contents of the DSGPR0 and
DSGPR1 holding registers will be lost.

4.4.1
The BOR bit always resets to ‘0’ on any V
or POR event. This makes it difficult to determine if a
Brown-out Reset event has occurred just by reading
the state of BOR alone. A more reliable method is to
simultaneously check the state of both POR and BOR.
This assumes that the POR bit is reset to ‘1’ in software
immediately after any Power-on Reset event. If BOR is
‘0’ while POR is ‘1’, it can be reliably assumed that a
Brown-out Reset event has occurred.
If the voltage regulator is disabled (LF devices), the

the BOR bit cannot be used to determine a Brown-out
Reset event. The BOR bit is still cleared by a Power-on
Reset event.
