10.3.2. Example: Write EEPROM command
8664C–CRYPT–01/10
These status words indicate the state of the device at the end of the command. In normal conditions, the device sends
the INS byte as the procedure byte, and $90 $00 as the final status word. In certain conditions described below, the
device may interrupt the command by returning a status word in place of INS as the procedure byte.
$67 $00 is returned as a procedure byte when the number of data bytes to be transferred is incorrect.
$69 $00 is returned after read/write commands as procedure bytes if the host is not allowed to read/write at the
address provided. It is also returned after Password commands if the maximum number of attempts has been
exceeded. The device will return $69 $00 as a final status word in place of $90 $00, if the password presentation failed.
$6B $00 is returned as procedure bytes if the address is incorrect.
$6D $00 is returned as procedure bytes if the INS code received is not supported.
The following illustrates the data exchanges that occur during a WRITE Operation of 4-bytes: $04, $09, $19, $97 to
addresses $02, $03, $04, $05 in the current user zone.
