The 5 registers of SPI3 (SPI 3), from 0xBF821400, with their reset value and every field. The PIC32MZ1024ECM124 has 1605 registers in 94 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.
