Upon receipt of this command, the device sets the BSY bit of Status register and saves the parameters. Then the device clears the BSY bit and generates an interrupt. When the SC register is specified to X'00', an ABORTED COMMAND error is posted. Other than X'00' is specified, this command terminates normally. The parameters set by this command are retained even after reset or power save operation regardless of the setting of disabling the reverting to default setting. The device ignores the L bit specification and operates with only CHS mode specification. C141-E192-02EN 5-31
