Bit 0
Search for ATA devices when VBUS returns. If this bit is set,
the ATA bus is searched for ATA devices every time
VBUS_ATA_ENABLE is asserted. This feature enables the
AT2LP to be used in designs where the drive may be physi-
cally removed (such as docking stations or port replicators).
0 = Search ATA bus on VBUS_ATA_ENABLE assertion
1 = No ATA bus search on VBUS_ATA_ENABLE assertion
Must be set to 0x00
