Part Number: LM8300
We have been using this component (LM8300IMT9B/NOPB) for a number of years and have always received a $C7 2 6 5 response to the read software revision command $B2. Recently we have come across some units that return $C7 0 0 0, is there a notification that explains this change and why it was made. Below is a snippet from the datasheet.
This command allows the user to read all the selected parameters. It is primary intended to aid in debugging.
This command can also be used if a configuration utility needs to determine the current setting of controller.
$B2: Read software version number
Reply Byte #1: $C7 (Software version number)
Byte #2: First byte in version number, year 20 (00-99)
Byte #3: Second byte in version number, month (1-12)
Byte #4: Third byte in version number, day (1-31)
