When programmed to any mode except
tsplink.TRIG_BYPASS
, the output state of the I/O line is
controlled by the trigger logic, and the user-specified output state of the line is ignored.
When the trigger mode is set to
tsplink.TRIG_RISING
, the user-specified output state of the line
is examined. If the output state selected when the mode is changed is high, the actual mode used will
be
tsplink.TRIG_RISINGA
. If the output state selected when the mode is changed is low, the
actual mode used will be
tsplink.TRIG_RISINGM
.
mode
stores the trigger mode as a numeric value when the attribute is read.
To control the line state, use the
tsplink.TRIG_BYPASS
mode with the
tsplink.writebit()
and the
tsplink.writeport()
commands.
Example
tsplink.trigger[3].mode = tsplink.TRIG_RISINGM
Sets the trigger mode for
synchronization line 3 to
tsplink.TRIG_RISINGM
.

This attribute indicates if the event detector ignored an event while in the detected state.

Usage
overrun = tsplink.trigger[ N ].overrun
overrun
Trigger overrun state
N
The trigger line (1 to 3)
Details
This command indicates whether an event has been ignored because the event detector was already
in the detected state when the event occurred.
This is an indication of the state of the event detector built into the synchronization line itself.
It does not indicate if an overrun occurred in any other part of the trigger model, or in any other
construct that is monitoring the event. It also is not an indication of an output trigger overrun.
