(4)Mode = 0, 1, 0, 0: Microcode download, without saving

In this mode, the controller’s microcode or control information is transferred to the IDD’s control memory area. “0” must be specified in the “Buffer ID” field and the “Buffer address” field.

The "Transfer byte length" field specifies the total number of transfer bytes of data transferred from the INIT.

When downloading of microcode is completed, the IDD generates a UNIT ATTENTION condition for all the INITs. At this time, the IDD performs microprogram reboot and generates sense code.

The IDD operates according to this microcode until its power is switched off. If the power is switched on again, the IDD’s operation returns to the existing microcode saved previously on the disk.

Note:

Depending on the setting in the IDD, if done using the START/STOP command, it is necessary to issue the START command after issuing his command. See the description of the motor starting modes in Section 5.3.2 of the “Product Manual” concerning the setting terminal.

(5)Mode = 0, 1, 0, 1 : Microcode download, with saving

In this mode, the controller’s microcode or control information is transferred to the IDD’s control memory area and written to the disk. “0” must be specified in the “Buffer ID” field and the “Buffer address” field.

The "Transfer byte length" field specifies the total number of transfer bytes of data transferred from the INIT.

When all the data have been received, the IDD writes the new microcode to the disk’s system area and operates in accordance with this microcode until new microcode is downloaded.

Note:

When abnormal termination for reasons other than ILLEGAL REQUEST [=5] / Invalid field in CDB [=24-00] or ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00] occurs, the IDD indicates that downloading of the new microcode failed, and it is therefore necessary for the INIT to quickly download the new microcode.

When downloading of microcode is completed, the IDD generates a UNIT ATTENTION condition for all the INITs except the INIT that issued the WRITE BUFFER command. At this time, the sense code indicates “Microcode has been changed [=3F-01].”
