The Cylinder Low register is set by the host to specify the cylinder number low
byte. Following an ATA command, the content of the register is written by the
device, identifying the cylinder number low byte.
In LBA mode, the 8-bit register maintains the contents of the Logical Block
number address bits A15:A08.
