PIC32MM0256GPM064 CFG registers

The 3 registers of CFG (Configuration and pin control), from 0xBF803640, with their reset value and every field. The PIC32MM0256GPM064 has 433 registers in 53 peripherals, one page each.

Most PIC32 SFRs have three more registers right after them: CLR at +4, SET at +8 and INV at +C (T1CONCLR, T1CONSET, T1CONINV), which clear, set or flip just the bits written as 1, in one write.
