PIC32MX170F512H TMR4 registers

The 3 registers of TMR4 (Timer 4), from 0xBF800C00, with their reset value and every field. The PIC32MX170F512H has 458 registers in 53 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.
