Timer 3 Capture Register

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

ture 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.
