The 6 registers of PMD (Peripheral module disable), from 0xBF80F240, with their reset value and every field. The PIC32MX250F256L has 514 registers in 57 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.
