PIC32MX575F512L configuration bits

The configuration words (DEVCFG0 to DEVCFG3, and on the newer chips the code-protect, signature and boot words) sit in boot flash and set the oscillator and PLL, the watchdog, the debugger pins, code protection and the peripheral options the chip starts with. Pick a setting and the word below updates; the starting values are the defaults in Microchip's device file, and an erased bit reads 1. In XC32 each setting is a #pragma config FNOSC = FRCPLL line.
