Summary of Configuration Bit Settings for the Enhanced Mid-Range PIC® MCU Using the XC8 Compiler
Below 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 in the "Configuration Bits" page of the enhanced mid-range tutorial.
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.
