The counter value restarts from 0 or the CRR shadow
register value depending upon the counter mode on
the rising edge of the STI signal. The registers will
also be updated.
The counter starts to count when the selected trigger
input STI is high. The counter stops counting on the
instant, not being reset, when the STI signal changes
its state to a low level. Both the counter start and stop
control are determined by the STI signal.
The counter starts to count from the original value in
the counter on the rising edge of the selected trigger
input STI. Only the counter start control is determined
by the STI signal.
The rising edge of the selected trigger signal STI will
clock the counter.
