The 1 register of CMP4 (Comparator 4), from 0xBF82C070, with their reset value and every field. The PIC32MK0128MCA048 has 785 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.
