Timer 3 Capture Register
The counter content can be read via the capture register. There are two ways to use the capture
register. In mode 1 and mode 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.
