The value should be 05000h in every buffer ID (00h thru 08h). It may also be set 0000h in which case no
code is updated.
If an invalid value is specified, the command is terminated with C H E C K C O N D I T I O N status. File shall
set sense key to ILLEGAL REQUEST and additional sense code to ILLEGAL F I E L D IN CDB.
7.37.4.3 Download EEPROM Data and Save (Buffer_ID = 80h)
Buffer ID must be set to 80h for the E E P R O M data.
Buffer Offset must be the even number between 00h and 7Eh.
Parameter List Length specifies the total bytes of E E P R O M Data to be saved. It must be less than or equal
to 80h.
7.37.4.4 Download Reserved Area Data and Save (Buffer_ID = 81h)
Buffer ID must be set to 81h for Reserved Area Data.
Buffer Offset must be zero.
Parameter List Length must be the total bytes of Reserved Area Data and the multiple of 512 bytes in
length.
7.37.4.5 Download ROM code and Flas-ROM update (Buffer_ID = 82h)
The file have a capability to update the Flash-ROM code by Write Buffer. This is affected only for the
customer who's file are consist of Flash-ROM version of the logic card.
It will take about 20 seconds to finish the command. After completion of the command, the file will start
as "Power on Reset" and running with newly downloaded R O M code. However R A M / Overlay code /
reserved area data in the file may not compatible with the new R O M code. In this case, file is running as
degraded and new R A M / Overlay code / reserved area data are needed to be download to be operational
with new code level.
Buffer ID must be set to 82h for R O M code.
Buffer Offset must be zero.
Parameter List Length must be the total bytes of R O M code. It should be 0C00h.
