Meaning
Error in the control byte or load value is greater than high counting limit
A status change of LD_STS_SLOT_<x> shows that a valid load request (LD_SLOT)
has been detected and executed.
Only in "Frequency measurement" operating mode (channel 0)
Status of the frequency value: (0 = frequency value is invalid; 1 = frequency value is
valid)
Status of the SW_GATE mirrored
Status of the internal gate (0 = gate closed, 1 = gate open), depending on the SW and
HW gate, when the HW gate is activated.
Logic for the comparison event DQ from the parameters
