The 4 registers of PORTB (I/O port B), from 0xBF886040, with their reset value and every field. The PIC32MX675F256H has 412 registers in 62 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.
