The sectors are transferred through the Data Register 16 bits at a time. If an uncorrectable error occurs, the write will be terminated at the failing sector. Output Parameters To The Device Sector Count Current The number of continuous sectors to be transferred low order, bits (7:0). Sector Count Previous The number of continuous sectors to be transferred high order bits (15:8). If zero is specified, then 65,536 sectors will be transferred. LBA Low Current LBA (7:0). LBA Low Previous LBA (31:24). LBA Mid Current LBA (15:8). LBA Mid Previous LBA (39:32). LBA High Current LBA (23:16). LBA High Previous LBA (47:40).
