5.5.2 Software Reset Operation

A software reset is performed by issuing a Reset Enable command (66H) followed by a Reset command (99H). Any command issued after the Reset Enable command, other than the Reset command, cancels the Reset Enable condition.

Once the Reset Enable and Reset commands are successfully executed, the device requires up to the maximum T_RECW time to return to its initial power-on state.
