SSD-HXXX(I)-3500 DATA SHEET

CYLINDER HIGH REGISTER

The Cylinder High register is set by the host to specify the cylinder number high byte. Following an ATA command, the content of the register is set internally by the device, identifying the cylinder number high byte.

In LBA mode, the 8-bit register maintains the contents of the Logical Block number address bits A23:A16.
