This command checks the power mode.
If the drive is in, going to, or recovering from the Standby Mode, the drive sets BSY, sets the Sector Count
register to 00h, clears BSY, and generates an interrupt.
If the drive is in the Idle Mode, the drive sets BSY, sets the Sector Count register to FFh, clears BSY, and
generates an interrupt.
