ATA REGISTERS

SSD-HXXX(I)-3500 DATA SHEET

SECTOR NUMBER REGISTER

The Sector Number register is set by the host to specify the starting sector number associated with the next ATA command to be executed. Following a qualified ATA command sequence, the device sets the register value to the last sector read or written as a result of the previous AT command.

When Logical Block Addressing (LBA) mode is implemented and the host issues a command, the contents of the register describe the Logical Block Number bits A[7:0]. Following an ATA command, the device loads the register with the LBA block number resulting from the last ATA command.
