The 7 registers of RTCC (Real-time clock and calendar), from 0xBF800000, with their reset value and every field. The PIC32MM0064GPM028 has 419 registers in 52 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.
