The 4 registers of PORTA (I/O port A), from 0xBF886000, with their reset value and every field. The PIC32MX564F064L has 521 registers in 61 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.
