17.17.1 Combined Header And Data (Mode 00000b) In this mode a 4-byte header followed by data bytes is returned to the Initiator during the DATA IN phase. The Buffer ID and the buffer offset field are reserved. The drive terminates the DATA IN phase when allocation length bytes of header plus data have been transferred or when the header and all available data have been transferred to the Initiator, whichever is less. The 4-byte READ BUFFER header (see figure below) is followed by data bytes from the data buffer of the drive. Table 111: Read Buffer Header Bit Byte 7 6 5 4 3 2 1 0 RSVD = 0 (MSB) 1-3 Buffer Capacity (LSB) The buffer capacity specifies the total number of data bytes that are available in the data buffer of the drive. This number is not reduced to reflect the allocation length nor is it reduced to reflect the actual number of bytes written using the WRITE BUFFER command. Following the READ BUFFER header the drive will transfer data from its data buffer. 17.17.2 Read Data (Mode 00010b) In this mode, the DATA IN phase contains buffer data. • Buffer ID field must be set to zero, indicating the data transfer buffer. If another value is specified, the command is terminated with Check Condition status. The drive shall set 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. The drive shall set sense key to Illegal Request and additional sense code to Illegal Field in CDB. • Allocation Length The drive terminates the DATA IN phase when allocation length bytes of data have been transferred or when the header and all available data have been transferred to the Initiator, whichever is less.

17.17.1

Combined Header And Data (Mode 00000b)

In this mode a 4-byte header followed by data bytes is returned to the Initiator during the DATA IN phase. The Buffer ID and

the buffer offset field are reserved.

The drive terminates the DATA IN phase when allocation length bytes of header plus data have been transferred or when the

header and all available data have been transferred to the Initiator, whichever is less.

The 4-byte READ BUFFER header (see figure below) is followed by data bytes from the data buffer of the drive.

Table 111:

Read Buffer Header

The buffer capacity specifies the total number of data bytes that are available in the data buffer of the drive. This number is not

reduced to reflect the allocation length nor is it reduced to reflect the actual number of bytes written using the WRITE

BUFFER command.

Following the READ BUFFER header the drive will transfer data from its data buffer.

17.17.2

Read Data (Mode 00010b)

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

•

Buffer ID

field must be set to zero, indicating the data transfer buffer. If another value is specified, the command is

terminated with

Check Condition

status. The drive shall set 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. The drive shall set sense key to

Illegal Request

and addi-

tional sense code to

Illegal Field in CDB

•

Allocation Length

The drive terminates the DATA IN phase when allocation length bytes of data have been trans-

ferred or when the header and all available data have been transferred to the Initiator, whichever is less.
