Details
Setting the pulse width to zero (0) seconds asserts the trigger indefinitely. To release the trigger line,
use trigger.digout[N].release().
Example
digio.line[4].mode = digio.MODE_TRIGGER_OUT
trigger.digout[4].pulsewidth = 20e-6
Sets the pulse width for trigger line 4 to
20

Digital I/O trigger line (1 to 6)
Details
Releases a trigger that was asserted with an indefinite pulsewidth time. It also releases a trigger that
was latched in response to receiving a synchronous mode trigger. Only the specified trigger line is
affected.
