This function sets LXI Trigger Bus lines that will be latched for LXI Limit Event outputs. When latching is enabled,
the trigger line is driven high when the first over-limit condition occurs and remains high until the instrument is reset
or until the next measurement sequence is initiated. When latching is disabled, the state of the trigger line is decided
once per scan and. when all chosen limit conditions are satisfied, the line is driven low. Implemented in firmware
version 1.4.0.
