Using This Function
CTR_Stop
suspends the operation of the counter in such a way that the counter can be
restarted by
CTR_Restart
and continue in its operation. For example, if a counter is set up
for frequency output, issuing
CTR_Stop
causes the counter to stop generating a square wave,
and
CTR_Restart
allows it to resume.
CTR_Stop
causes the counter output to remain at the
state it was in when
CTR_Stop
was issued.
Note
Because of hardware limitations,
CTR_Stop
cannot stop a counter generating a
square wave with period1 of 1 and period2 of 1.
