Issue with Access - "pin is not writable" Error when using setp

Where in Linux are these signals generated, and how can I configure them for a specific driver? At what point do I need to inform Linux that the driver should specifically use control word 0Fh? I need to insert 0Fh into 6040, but it doesn't seem to work.

If I turn on the machine with a button, why doesn't the control word value change? Please explain to me not where the signals are transmitted, but how to send a specific value to the control word.
