Command execution is identical to the Write Sector(s) Ext command except that an interrupt is generated for each block (as defined by the Set Multiple command) instead of for each sector. The sectors are transferred through the Data Register 16 bits at a time. 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 in the Sector Count register, then 65,536 sectors shall 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). Input Parameters From The Device LBA Low (HOB=0) LBA (7:0) of the address of the first unrecoverable error.
