PIC16F690 configuration bits The configuration words set the oscillator, the watchdog, the power-up timer, brown-out reset, low-voltage programming and code protection. Pick a setting and the word below updates; the starting values are the defaults in Microchip's device file. In XC8 each setting is a #pragma config NAME = SETTING line.
