Measuring Input TO - Part III
5.3 Configuring the Measuring Input technology object
● The measuring process is terminated with _disableMeasuringInput.
● The edges fall outside the measuring range.
● No enable signal is present (gate closed).
It is also possible to execute the enable with inverted logic, i.e. the enable input on the TM17
High Feature can be operated inversely and then works in LOW-active mode.
Overriding the enable
It is possible to override the measuring enable input with a software enable signal. To do this,
you have to access the input directly via its address and set the bit. The enable is achieved,
as long as the bit is set (functions as enable input).
