Feature register
The feature register is a write-only register, located at address 1F1h [171h], offset 1h, Dh.
This write-only register provides information on features that the host can utilize. It is
accessed on data bits D15 to D8 during a write operation to Offset 0 with –CE2 Low and –
CE1 High.
Sector count register
The sector count register is located at address 1F2h [172h], offset 2h.
This register contains the number of sectors of data to be transferred on a read or write
operation between the host and card. If the value in this register is zero, a count of 256
sectors is specified. If the command was successful, this register is zero at completion. If not
successfully completed, the register contains the number of sectors that need to be
transferred in order to complete the request. The default value is 01h.
Sector number (LBA 7-0) register
The sector number register is located at address 1F3h [173h], offset 3h.
This register contains the starting sector number or bits 7 to 0 of the logical block address
(LBA), for any data access for the subsequent sector transfer command.
Cylinder low (LBA 15-8) register
The cylinder low register is located at address 1F4h [174h], offset 4h.
This register contains the least significant 8 bits of the starting cylinder address or bits 15 to
8 of the logical block address.
Cylinder high (LBA 23-16) register
The cylinder high register is located at address 1F5h [175h], offset 5h.
This register contains the most significant bits of the starting cylinder address or bits 23 to
16 of the logical block address.
