PIC32MK1024MCF100 PMP registers

The 10 registers of PMP (Parallel master port), from 0xBF82E000, with their reset value and every field. The PIC32MK1024MCF100 has 1917 registers in 121 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.
