This bit is set to “1”.
LBA is a flag to select either Cylinder/Head/Sector (CHS) or
Logical Block Address (LBA) mode. When LBA =0, CHS mode
is selected. When LBA=1, LBA mode is selected. In LBA
mode, the Logical Block Address is interrupted as follows:
This bit is set to “1”.
This bit is used for selecting the Master (Card 0)and
Slave(Card 1) in Master/Slave organization. The card is set
to be Card 0 or 1 by using DRV# of the Socket and Copy
register.
This bit is used for selecting the Head number for the
following command. Bit 3 is MSB.
