The 4 registers of PORTA (I/O port A), from 0xBF886000, with their reset value and every field. The PIC32MX575F512L has 569 registers in 65 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.
