A set bit indicates that the specified line generated an action overrun when triggered to generate an output
trigger.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
Status register set contents (on
page E-1) and Enable and transition registers (on page E-19). The individual bits of this register are defined in
the following table.
Bit Value Description
B0 Not used Not applicable
B1
status.operation.instrument.tsplink.trigger_overrun.LINE1
Bit B1 decimal
value: 2
B2 status.operation.instrument.tsplink.trigger_overrun.LINE2 Bit B2 decimal
value: 4
B3 status.operation.instrument.tsplink.trigger_overrun.LINE3 Bit B3 decimal
value: 8
B4-B15 Not used Not applicable
As an example, to set bit B1 of the operation status TSP-Link overrun enable register, set
status.operation.instrument.tsplink.trigger_overrun.enable =
status.operation.instrument.tsplink.trigger_overrun.LINE1
.
In addition to the above constants,
operationRegister
can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set
operationRegister
to the sum of their decimal weights. For
example, to set bits B1 and B3, set
operationRegister
to 10 (which is the sum of 2 + 8).

Example 1
status.operation.instrument.tsplink.trigger_overrun.enable =
status.operation.instrument.tsplink.trigger_overrun.LINE1 Uses a constant
to set the line 1
bit of the
operation status
TSP-Link
overrun enable
register.
