The 14 registers of PORTA (I/O port A), from 0xBF860000, with their reset value and every field. The PIC32MZ2048EFM144 has 1692 registers in 94 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.
