17.45.1 Combined Header And Data (Mode 00000b) In this mode, the data to be transferred is preceded by a four-byte header. Buffer ID must be zero. If another value is specified, no download function is performed and the command is terminated with Check Condition status. And the drive shall set the sense key to Illegal Request and additional sense code to Illegal Field in CDB. Buffer Offset must be zero. If another value is specified, no download function is performed and the command is terminated with Check Condition status. And the drive shall set the sense key to Illegal Request and additional sense code to Illegal Field in CDB. Parameter List Length specifies the number of bytes that shall be transferred during the DATA OUT phase. This number includes four bytes of header, so the data length to be stored in the drive buffer is transfer length minus four. If the length exceeds the buffer size, the command is terminated with Check Condition status. And the drive shall set sense key to Illegal Request and additional sense code to Illegal Field in CDB. A Parameter List Length of less than four (size of header) indicates no data is transferred. The 4-byte header consists of all reserved bytes.

Combined Header And Data (Mode 00000b)

In this mode, the data to be transferred is preceded by a four-byte header.

Buffer ID

must be zero. If another value is specified, no download function is performed and the command is terminated with

Check Condition

status. And the drive shall set the sense key to

Illegal Request

and additional sense code to

Illegal Field in

CDB

Buffer Offset

must be zero. If another value is specified, no download function is performed and the command is terminated

with

Check Condition

status. And the drive shall set the sense key to

Illegal Request

and additional sense code to

Illegal Field

in CDB

Parameter List Length

specifies the number of bytes that shall be transferred during the DATA OUT phase. This number

includes

four bytes of header, so the data length to be stored in the drive buffer is transfer length minus four. If the length

exceeds the buffer size, the command is terminated with

Check Condition

status. And the drive shall set sense key to

Illegal

Request

and additional sense code to

Illegal Field in CDB

. A Parameter List Length of less than four (size of header) indicates

no data is transferred.

The 4-byte header consists of all reserved bytes.

Table 163: Write Buffer Header

17.45.2

Write Data (Mode 00010b)

In this mode, the DATA OUT phase contains buffer data.

Buffer ID

must be zero. If another value is specified, no download function is performed and the command is terminated with

Check Condition status. And the drive shall set the sense key to

Illegal Request

and additional sense code to

Illegal Field In

CDB.

Buffer Offset

specifies the offset of the memory space specified by the Buffer ID. The initiator should conform to the offset

boundary requirements returned in the READ BUFFER descriptor. If the value exceeds the buffer specified, the command is

terminated with

Check Condition

status. And the drive shall set the sense key to

Illegal Request

and additional sense code to

Illegal Field In CDB.

Parameter List Length

specifies the Parameter List Length. It must be

•

less than the capacity of the buffer size after adding the Buffer Offset value and

•

on a sector boundary

A Parameter List Length of zero indicates no data is to be transferred and command status is returned.

If an invalid value is specified, the command is terminated with

Check Condition

status. And the drive shall set the sense key

Illegal Request

and additional sense code to

Illegal Field In CDB.
