The MCLR pin provides a method for triggering an external Reset of the device by Break PIC18F4331 Microprocessor Eeprom Memory. 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 when Crack MCU Firmware.
The MCLR pin is not driven low by any internal Resets, including the WDT.
In PIC18F4331 devices, the MCLR input can be disabled with the MCLRE Configuration bit. When MCLR is disabled, the pin becomes a digital input. See Section 10.5 “PORTE, TRISE and LATE Registers” for more information.

A Power-on Reset pulse is generated on-chip whenever VDD rises above a certain threshold after Break PIC18F2510 Microcontroller Flash Memory. This allows the device to start in the initialized state when VDD is adequate for operation.

To take advantage of the POR circuitry, tie the MCLR pin through a resistor (1 kÙ  to 10 kÙ) to VDD. This will eliminate external RC components usually needed to create a Power-on Reset delay for the purpose of Copy PIC18F2480 MCU Locked Heximal. A minimum rise rate for VDD is specified (parameter D004). For  a  slow rise time, see below Figure.

When the device starts normal operation (i.e., exits the Reset condition), device operating parameters (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 for the purpose of Losted PIC18F2458 Microcontroller Embedded Code Restoration.

POR events are captured by the POR bit (RCON<1>). 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 manually resets the bit to ‘1’ in software following any POR by Microcontroller PIC18F2439 Code Reverse Engineering.
