WHAT THE AUTOLOADER RETURNS
Sense Key Specific – Byte 15, Bits 6 through 0; Bytes 16 and 17
When the SKSV bit is set to 1, the information contained in this field indicates
which field in the CDB or parameter list of a command caused the Check
Condition status. This field, valid only for a sense key of Illegal Request (5h), is
defined as follows:
C/D (Command/Data) – Byte 15, Bit 6 Indicates whether the Check
Condition status resulted from an illegal parameter in either the command
descriptor block (Command) or the parameter list (Data) of a particular
command, as follows:
0 – The Check Condition status resulted from an illegal parameter in the
parameter list (Data).
1 – The Check Condition status resulted from an illegal parameter in the
command descriptor block (Command).
BPV (Bit Pointer Valid) – Byte 15, Bit 3 Indicates whether the value in the Bit
Pointer field is valid, as follows:
0 – The value contained in the Bit Pointer is not valid.
1 – The value contained in the Bit Pointer (byte 15, bits 2 through 0) is valid.
The value in the Bit Pointer field is valid when the field of the CDB or
parameter list that caused the error is less than one byte long.
Bit Pointer – Byte 15, Bits 2 through 0 Specifies the bit of the byte identified
by the Field Pointer (bytes 16 and 17). When a multiple-bit field is in error, the
Bit Pointer contains the value of the most significant bit of the field. The most
significant bit of a multiple-bit field is the bit with the highest bit number. For
example, if a field consists of bits 5, 4, and 3, the most significant bit is bit 5.
Field Pointer – Bytes 16 and 17 Contains the number of the byte in which
the error occurred. Byte numbers start at 00. When a multiple-byte field is in
error, the Field Pointer contains the value of the most significant byte of the
field. The most significant byte of a multiple-byte field is the byte with the
lowest byte number. For example, if a field consists of bytes 02, 03, and 04, the
most significant byte is byte 02.
