register contains current LBA bits 24 - 27. (L=1)
H
The cylinder number of the sector to be transferred. (L=0) In LBA mode, this
register contains current LBA bits 8 - 15 (Low), 16 - 23 (High). (L=1)
Cylinder High/Low
The sector number of the sector to be transferred. (L=0) In LBA mode, this
register contains current LBA bits 0 - 7. (L=1)
Sector Number
The number of requested sectors not transferred.Sector Count
Input Parameters From The Device
The drive internally uses 40 bytes of ECC on all data read or writes. The 4-byte mode of operation is
provided via an emulation technique. As a consequence of this emulation it is recommended that a
40-byte ECC mode is used for all tests to confirm the operation of the files ECC hardware. Unexpected
results may occur if such testing is performed using a 4-byte mode.
