Timer 3 Capture Register The counter content can be read via the capture register. There are two ways to use the

capture register. In modes 1 and 4, it is possible to read the current counter value

directly out of the capture register. In the capture modes 2, 3, 5 and 12, a capture event

like an edge at the Timer 3 input or a signal from Timer 2 stores the current counter

value into the capture register. This counter value can be read from the capture register.
