Status Words
Table 8-3.
These status words indicate the state of the device at the end of the command. In normal condi-
tions, 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 sta-
tus word in place of INS as the procedure byte.
$67 $00 is returned as procedure bytes 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.
