Pulse sequence

Function
A maximum of 2 blocks of this type can be created.
A repetitive pulse sequence with configurable duration of the individual high and low phases
is sent to the output. The phase position of the first phase is always high. If the pulse
sequence is to begin with the phase position "Low", the first phase can also be configured
with the duration 0 or the output can be negated.
