Details
These attributes are used to read or write to the operation status TSP-link overrun registers. Reading a status
register returns a value. The binary equivalent of the returned value indicates which register bits are set. The
least significant bit of the binary number is Bit B0, and the most significant bit is Bit B15. For example, if a value
of 10 is read as the value of the condition register, the binary equivalent is 0000 0000 0000 1010. This value
indicates that bit B1 and bit B3 are set.

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

B3

B15
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).
