WFI32E02 PCACHE registers The 4 registers of PCACHE (Prefetch cache), from 0xBF812400, with their reset value and every field. The WFI32E02 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.
