23.2
The MCLR pin provides a method for triggering an
external Reset of the device. A Reset is generated by
holding the pin low. These 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.
In PIC18F/LF1XK50 devices, the MCLR input can be
disabled with the MCLRE Configuration bit. When
MCLR is disabled, the pin becomes a digital input. See
Section 9.1 “PORTA, TRISA and LATA Registers”
for more information.

V
To take advantage of the POR circuitry, tie the MCLR
pin through a resistor (1 k to 10 k) to V
eliminate external RC components usually needed to
create a Power-on Reset delay.
When the device starts normal operation (i.e., exits the
Reset condition), device operating parameters (volt-
age, 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 of the RCON
register. The state of the bit is set to ‘0’ whenever a
POR 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 must manually set
the bit to ‘1’ by software following any POR.
