5.2.1 2-byte Config Bits Registers

Configuration Registers with 2 Bytes

5.2.1.1 Introduction

The Configuration settings allow the user to select the oscillators, reset sources and memory protection from the several options available on the device. They are latched in place at the power-up and also after programming of the device.

5.2.1.4.1 CONFIGBITS Driver

This is the generated header file for the Configuration bits driver.

Module description

This is the generated header file for the Configuration bits driver.

Version: Driver Version 1.0.0
Note: The below code is an example code only and the value for each config bit setting will vary depending on the setup on the Configuration Bits module.

//CONFIG1
#pragma config FOSC = ECH    // Oscillator Selection->ECH, External Clock, High Power Mode (4-20 MHz): device clock supplied to CLKIN pins
#pragma config WDTE = OFF    // Watchdog Timer Enable->WDT disabled
#pragma config PWRTE = OFF    // Power-up Timer Enable->PWRT disabled
#pragma config MCLRE = ON    // MCLR Pin Function Select->MCLR/VPP pin function is MCLR
#pragma config CP = OFF    // Flash Program Memory Code Protection->Program memory code protection is disabled
#pragma config BOREN = ON    // Brown-out Reset Enable->Brown-out Reset enabled
#pragma config CLKOUTEN = OFF    // Clock Out Enable->CLKOUT function is disabled. I/O or oscillator function on the CLKOUT pin
#pragma config IESO = ON    // Internal/External Switchover->Internal/External Switchover Mode is enabled
#pragma config FCMEN = ON    // Fail-Safe Clock Monitor Enable->Fail-Safe Clock Monitor is enabled

//CONFIG2
#pragma config WRT = OFF    // Flash Memory Self-Write Protection->Write protection off
#pragma config PLLEN = OFF    // PLL Enable->4x PLL is disabled
#pragma config STVREN = ON    // Stack Overflow/Underflow Reset Enable->Stack Overflow or Underflow will cause a Reset
#pragma config BORV = LO    // Brown-out Reset Voltage Selection->Brown-out Reset Voltage (Vbor), low trip point selected.
#pragma config LVP = ON    // Low-Voltage Programming Enable->Low-voltage programming enabled
#pragma config LPBOR = OFF    // Low-Power Brown-out Reset Enable Bit->Low-Power BOR is disabled
#pragma config PPS1WAY = ON    // Peripheral Pin Select one-way control->The PPSLOCK bit cannot be cleared once it is set by software
#pragma config ZCD = OFF    // Zero-cross detect disable->ZCD disabled. ZCD can be enabled by setting the ZCDSEN bit of ZCDCON
#pragma config DEBUG = OFF    // In-Circuit Debugger Mode->In-Circuit Debugger disabled, ICSPCLK and ICSPDAT are general purpose I/O pins
