7i73 LCD shows rubisch

Before a DOIT command is written to start a data transfer cycle with the remote
device, the host must write its packed outgoing process data (OPD in table below) to the
interface registers. (The CS register not currently used for outgoing data/control so is not
written)

you are right, its in the cmd, not cs register. but the cmd register is also written before the data...

Yes.

But you are saying that your fix works?

so you suggest moving the hm2_sserial_setup_channel last in the sequence?

I cant test if it works, because I have no issue.
Im only looking at the packets send by hm2_eth.
I do understand that do it should be set after the data is written, thats what im trying to do.

That was my plan.

Or, possibly, to add a third function that appends just the command register. I am not clear if it is possible to setup the channel last.
