IDE0 Task File Data
This register defines one of the IDE Channel #0 Task File registers in the SiI 0680A. Access to the individual bytes of this
register is determined by the PCI bus Byte Enables at the time of the read or write operation. The register bits are defined
below.
Bit [31:00]
: IDE0 Task File Data (R/W). This bit field defines the IDE0 Task File Data register. This register can
be accessed as an 8-bit, 16-bit, or 32-bit word, depending upon the PCI bus Byte Enables. The data written to
this register must be zero-aligned. To access 8-bit Task File Data, the PCI bus Byte Enable for byte 0 must be
active. To access 16-bit Task File Data, the Byte Enables for byte 1 and byte 0 must be active. To access 32-bit
Task File Data, the Byte Enables for all four bytes must be active.
Bit [31:24]
: IDE0 Task File Starting Sector Number (R/W). This bit field defines the IDE0 Task File Starting
Sector Number register. Access to this bit field is permitted if the PCI bus Byte Enable is active for this byte only.
Bit [23:16]
: IDE0 Task File Sector Count (R/W). This bit field defines the IDE0 Task File Sector Count register.
Access to this bit field is permitted if the PCI bus Byte Enable is active for this byte only.
Bit [15:08]
: IDE0 Task File Features (W). This write-only bit field defines the IDE0 Task File Features register.
Access to this bit field is permitted if the PCI bus Byte Enable is active for this byte only.
Bit [15:08]
: IDE0 Task File Error (R). This read-only bit field defines the IDE0 Task File Error register. Access
to this bit field is permitted if the PCI bus Byte Enable is active for this byte only.

IDE0 Task File Cylinder High
IDE0 Task File Cylinder Low
This register defines one of the IDE Channel #0 Task File registers in the SiI 0680A. Access to these bit field is permitted if the
PCI bus Byte Enable is active for one byte only.
The register bits are defined below.
Bit [31:24]
: IDE0 Task File Command (W). This write-only bit field defines the IDE0 Task File Command
register.
Bit [31:24]
: IDE0 Task File Status (R). This read-only bit field defines the IDE0 Task File Status register.
Bit [23:16]
: IDE0 Task File Device+Head (R/W). This bit field defines the IDE0 Task File Device and Head
register.
Bit [15:08]
: IDE0 Task File Cylinder High (R/W). This bit field defines the IDE0 Task File Cylinder High register.
Bit [07:00]
: IDE0 Task File Cylinder Low (R/W). This bit field defines the IDE0 Task File Cylinder Low register.
