Check Power Mode — 98h, E5h

The Check Power Mode command verifies the device’s current power mode. When the device is configured for standby mode or is entering or exiting standby, the BSY bit is set, the Sector Count register set to 00h, and the BSY bit is cleared. In idle mode, BSY is set and the Sector Count register is set to FFh. The BSY bit is then cleared and an interrupt is issued.
