The 2 registers of JTAG (JTAG), from 0xBF812000, with their reset value and every field. The PIC32MZ1025W104132 has 1091 registers in 66 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.
