In the block diagram above only the most important elements are shown. The pin
out is shown for X41, but it is the same for X42, X43 and X44.
4.2.2 Specification
4.3 Counter Inputs
The F-FEM-DDC has 8 counter channels (one or two track) that are fed by the
16 digital input channels.
In addition, these Counter inputs have parameterizable digital filters for elimi-
nating spikes of variable length. This filter function is available only with PUMA
