Dual timers

The dual timer consists two programmable 32-bit or 16-bit Free-running counters(FRCs) that

can generate interrupts when they reach 0. There are two dual timers and 4 FRCs. One dual

timers has one interrupt handler, resulting in two interrupts of timers. Also one dual timer

has one clock but two clock enable signals. Users can select one repetition modes one-shot

or wrapping mode, and wrapping mode consists free-running and periodic mode. Two FRCs

are one set so two FRCs has one clock, reset, and interrupt but each FRC has an individual

clock enable.

One dual timer has two Free-Running Counters(FRCs).

One dual timer has one interrupt handler and one clock.

One dual timer has two clock enable signals.

There are 2 dual timers.

A 32-bit or a 16-bit down counter.

One of the following repetition modes: one-shot and wrapping mode.

One of the following wrapping modes: Free-running and periodic mode.

There is a prescaler that can divide down the clock rate by 1, 16, or 256.
