The programmable interrupt timer (PIT) is a 16-bit timer that provides
precise interrupts at regular intervals with minimal processor
intervention. The timer can either count down from the value written in
the modulus latch, or it can be a free-running down-counter.
This device has two programmable interrupt timers. PIT1 has a base
address located at 0x00c8_0000. PIT2 base address is 0x00c9_0000.
