The 26 registers of SQI (Serial quad interface), from 0xBF8E2000, with their reset value and every field. The PIC32MZ1064DAK176 has 2244 registers in 101 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.
