The 5 registers of UART6 (UART 6), from 0xBF822A00, with their reset value and every field. The PIC32MZ1024EFG144 has 1315 registers in 91 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.
