Reserved
This register defines one of the Channel X Task File registers used for Command Buffered accesses in the
SiI3114. The register bits are defined below.
Bit [31:24]: Task File Starting Sector Number (R/W). This bit field defines the Channel X Task File Starting
Sector Number register.
Bit [23:16]: Task File Sector Count (R/W). This bit field defines the Channel X Task File Sector Count
register.
Bit [15:08]: Task File Features (W). This write-only bit field defines the Channel X Task File Features
register.
Bit [07:00]: Reserved (R). This bit field is reserved and returns zeros on a read.

This register defines one of the Channel X Task File registers used for Command Buffered accesses in the
SiI3114. The register bits are defined below.
The Channel 0 and Channel 1 Device Select bits (bit 4 of the byte, bit 20 of this register) MUST be 0 for proper
operation of the Task File registers when accessed via Base Address 5. The Device Select bits in the Channel 2
or Channel 3 Device+Head Task File is ignored.
Bit [31:24]: Task File Command (W). This write-only bit field defines the Channel X Task File Command
register.
Bit [23:16]: Task File Device+Head (R/W). This bit field defines the Channel X Task File Device and Head
register.
Bit [15:08]: Task File Cylinder High (R/W). This bit field defines the Channel X Task File Cylinder High
register.
Bit [07:00]: Task File Cylinder Low (R/W). This bit field defines the Channel X Task File Cylinder Low
register.
