(6)Mode = 0, 1, 1, 0 : Microcode Download with offsets, without saving

In this mode the INIT may split the transfer of the controller's microcode or control information over two or more WRITE BUFFER commands.

If the last WRITE BUFFER command of a set of one or more commands completes successfully, the microcode or control information shall be transferred to the control memory space of the IDD.

Since the download microcode or control information may be sent using several commands, when the IDD detects the last download microcode with offsets, the IDD shall perform the verification of the complete set of downloaded microcode or control information prior to returning GOOD status for the last command. After the last command completes successfully the IDD generates a unit attention condition for all INITs except the one that issued the set of WRITE BUFFER commands. When reporting the unit attention condition, the IDD sets the additional sense code to

MICROCODE HAS BEEN CHANGED.

"0" must be specified in the "Buffer ID" field.

The microcode or control information is written to the logical unit buffer starting at the location specified by the BUFFER Address field. If the IDD is unable to accept the specified buffer address, it shall return CHECK CONDITION status and it shall set the sense key to ILLEGAL REQUEST [=5] with an additional sense code of INVALID FIELD IN CDB [=24-00].

The "Transfer Byte Length" field specifies the maximum number of bytes that shall be present in the Data-Out Buffer to be stored in the specified buffer beginning at the buffer offset. The INIT should attempt to ensure that the parameter list length plus the buffer offset does not exceed the capacity of the specified buffer. (The capacity of the buffer may be determined by the BUFFER CAPACITY field in the READ BUFFER descriptor.) If the BUFFER Address and Transfer Byte Length fields specify a transfer in excess of the buffer capacity, the IDD shall return CHECK CONDITION status and shall set the sense key to ILLEGAL REQUEST [=5] with an additional sense code of INVALID FIELD IN CDB [=24-00].

(7)Mode = 0, 1, 1, 1 : Microcode Download with offset, with saving

In this mode the INIT may split the transfer of the controller's microcode or control information over two or more WRITE BUFFER commands.

If the last WRITE BUFFER command of a set of one or more commands completes successfully, the microcode or control information shall be saved in a non-volatile memory space.

Since the downloaded microcode or control information may be sent using several commands, when the IDD detects the last download microcode with offsets and save mode WRITE BUFFER command has been received, the IDD shall perform the verification of the complete set of downloaded microcode or control information prior to returning GOOD status for the last command. After the last command completes successfully the IDD generates a unit attention condition for all INITs except the one that issued the set of WRITE BUFFER commands. When reporting the unit attention condition, the IDD sets the additional sense code to MICROCODE HAS BEEN CHANGED.
