It is a relatively complex driver, because it supports not only the scaler record interface, but also the mca record interface.  The driver allows the SIS3820 to be used as a simple preset scaler (like the Joerger VSC16).  It also allows it to be used as a multi-channel scaler (MCS), with each input counting into an array as a function of time or external channel advance.  The time per point can be as small as 1 microsecond or so.

Thank you Mark, this looks very good for a reference. I'd only been
looking inside the std/ top-level directory, which is why I hadn't seen
it.

Cheers,

Angus
