^^^^^^^^^^^^
MASTER_MODE is BIT(13). It's unclear what this is supposed to be. My
best guess is that the ! should just be deleted.
This ! is intentional because it is meant to be Slave mode. Would a better approach be to create another #define for slave mode?
In my opinion, it's better to just leave it out. ORing with zero causes
a different static checker warning on my unreleased checks... Is it
0 << 13? I feel like ORing with zero just makes things more confusing.
It is 0<<13, in the event it was previously configured to Master I would need to unset the bit
You are assigning the result to write_val, so there's no memory of what
was configured before?
