Manual Reset: If selected, enables the reset request after each activation of the device.
Otherwise, enabling of the output follows directly the conditions of the inputs. Reset may
be of two types: Manual and Monitored. Selecting the Manual option, only transition of
the signal from 0 to 1 is checked. If Monitored is selected, double transition from 0 to 1
and return to 0 is checked.

WARNING: if Reset is enabled, the input consecutive to those used by the functional
block must be used. For example: If inputs 1 and 2 are used for the functional
block, input 3 must be used for Reset.
