Reset Request
If RST = 1, a reset operation begins. This bit clears when the reset
operation is complete and the NOATR bit can be read to verify that a
slave responded.
If this bit is set at the same time as the OP bit is set, the reset runs first
and the operation starts when reset has completed. If this bit is written
when an operation is already in progress, it cancels the operation and
starts the reset.
