ATA REGISTERS

SSD-HXXX(I)-3650 DATA SHEET

CYLINDER LOW REGISTER

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.
