Enable i2c module/unit before transmission and disable when it
finishes.
why?
It's because the i2c bus may be disturbed if the slave device,
typically a touch, powers on.
Why should that be an issue?
Is it an errata.
Not I am aware of.
In which mode it is an issue slave / master or both?
since it talks about touch, I expect it to be master mode.
Thanks,
