This number is used by the TSP-Link trigger line when it detects an input trigger.
Set the stimulus of any trigger event detector to the value of this constant to have it respond to trigger events
from this line.

Description
tsplink.TRIG_BYPASS 0
Allows direct control of the line as a digital I/O line.
tsplink.TRIG_FALLING 1
Detects falling-edge triggers as input. Asserts a TTL-low pulse
for output.
tsplink.TRIG_RISING 2
If the programmed state of the line is high, the
tsplink.TRIG_RISING
mode behaves similar to
tsplink.TRIG_RISINGA
. If the programmed state of the line
is low, the
tsplink.TRIG_RISING
mode behaves similar to
tsplink.TRIG_RISINGM
. Use
digio.TRIG_RISINGA
if
the line is in the high output state. Use
digio.TRIG_RISINGM
if the line is in the low output state.
tsplink.TRIG_EITHER 3
Detects rising- or falling-edge triggers as input. Asserts a
TTL-low pulse for output.
tsplink.TRIG_SYNCHRONOUSA 4
Detects the falling-edge input triggers and automatically
latches and drives the trigger line low.
tsplink.TRIG_SYNCHRONOUS 5
Detects the falling-edge input triggers and automatically
latches and drives the trigger line low. Asserts a TTL-low pulse
as an output trigger.
