8.4.2 Starting a count
A count can be started by using a command or TC7 pin input.
8.4.2.1 Command start and capture mode
(1) Description
Writing a 1 to TC7ST causes the current count to be cleared and the counter to start counting. Once
the count has reached a specified period, the counter is cleared. The counter subsequently restarts
counting if STM specifies continuous mode; it stops counting if STM specifies one-time mode.
Writing a 1 to TC7ST before the count reaches a period causes the counter to be cleared, after
which it operates as specified with STM.
The count values at the rising and falling edges on the TC7 pin can be stored in capture registers
(Details for the capture are given in a separate section).
