The 4 registers of PORTC (I/O port C), from 0xBF886080, with their reset value and every field. The PIC32MX564F064H has 506 registers in 58 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.
