Error information
*1) Data Transfer Mode
The host sets X’03’ to the Features field. By issuing this command with setting a
value to the Sector Count field, the transfer mode can be selected. Upper 5 bits of
the Sector Count register defines the transfer type and lower 3 bits specifies the
binary mode value.
The IDD supports following values in the Sector Count field value. If other value
than below is specified, an ABORTED COMMAND error is posted.
Note: For a serial ATA device, the setting of a data transfer mode is reflected in
WORD 63 and 88 in IdentifyDevice information. However, the actual
data transfer rate depends on the serial ATA signaling rate in WORD 76
in IdentifyDevice information.
