The 5 registers of CFG (Configuration and pin control), from 0xBF800000, with their reset value and every field. The PIC32MK0512MCF064 has 1844 registers in 120 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.
