The 2 registers of REFO5 (Reference clock output 5), from 0xBF801300, with their reset value and every field. The PIC32MZ2025DAB288 has 2318 registers in 103 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.
