H The head number of the first sector to be transferred. ( L = 0 ) In LBA mode, this register contains LBA bits 24 - 27. ( L = 1 ) R The retry bit. If set to one, then retries are disabled. When write cache is enabled, They are ignored. (Ignoring the retry bit is in violation of ATA-3.) Input Parameters From The Device Sector Count The number of requested sectors not transferred. This will be zero, unless an unrecoverable error occurs. Sector Number The sector number of the last transferred sector. ( L = 0 ) In LBA mode, this register contains current LBA bits 0 - 7. ( L = 1 ) Cylinder High/Low The cylinder number of the last transferred sector. ( L = 0 ) In LBA mode, this register contains current LBA bits 8 - 15 (Low), 16 - 23 (High). (L=1) H The head number of the last transferred sector. ( L = 0 ) In LBA mode, this register contains current LBA bits 24 - 27. ( L = 1 ) Command Descriptions 161
