8-bit Enhanced Mid-Range PIC16F1xxx Configuration Bit Settings Using MPLAB® XC8 Compiler

Last modified by Microchip on 2024/01/29 14:08

Here is a summary of the PIC16F1xxx configuration bit directives accepted by Microchip's MPLAB^®XC8 C compiler.

A comprehensive description of these configuration bit settings is presented on the 8-bit Enhanced Mid-Range PIC16F1xxx Configuration Bits page.

Tip: Some enhanced mid-range PIC^® MCUs may have a different set of configuration bits. Check the datasheet of the MCU you are using to get a complete list.

#pragma config CONFIG_BIT_NAME = CONFIG_VALUE

CONFIG_BIT_NAME	CONFIG_VALUE	Function of the configuration bits
FOSC	INTOSC EXTRC HS XT LP ECH ECM ECL	Internal Oscillator is the clock source External R-C Oscillator is the clock source External High Seed Crystal/Oscillator External Crystal/Oscillator External Low Power oscillator External Clock w/ frequency range 4 - 32 MHz External Clock w/ frequency range 0.5 - 4 MHz External Clock w/ frequency range 0 - 0.5 MHz
WDTE	ON OFF NSLEEP SWDTEN	Watchdog Timer (WDT) is disabled WDT is enabled WDT is enabled when running and disabled when in SLEEP mode WDT controlled by the SWDTEN bit in the WDTCON register
