#### Cin/Mask Explanation
|
|
|
|
When valid bits are set in the Mask input, the filter module will use the corresponding bits from the Cin input instead of the normal `_SW1` and `_SW2` EPICS channels. This allows the realtime model to control a subset of the filters control flags. When these options are controlled in this manner, we call it being under "local control". The medm screens will draw a yellow "LC" by elements displayed on the filter screen that are being masked (corresponding bits high in Mask input).

This is the same bit order as the `cdsFiltCtrl`, however there are now three additional most significant bits that mask/control if the module should use the offset, gain and ramp provided by the realtime model instead of the EPICS inputs.
