| CLA | As defined in 5.4.1 |
| INS | ‘C0’ |
| P1-P2 | ‘0000’ (other values are RFU) |
| Lc field | Empty |
| Data field | Empty |
| Le field | Maximum length of data expected in response |
Table 75 – GET RESPONSE response APDU
| Data field | (Part of) APDU according to Le |
| SW1-SW2 | Status bytes |
The following specific normal processing may occur :
SW1=’61’ with SW2
The following specific warning condition may occur :
SW1=’62’ with SW2=
The following specific error conditions may occur.
SW1=’67’ with SW2=

| P1-P2 | ‘0000’ (other values are RFU) |
| Lc field | Length of the subsequent data field |
| Data field | (Part of) APDU |
| Le field | Empty of length of expected data |
When the ENVELOPE command is used under T=0 for transmitting data strings, an empty data field in an ENVELOPE command APDU means end of data string.
Table 77 – ENVELOPE response APDU
| Data field | Empty or (part of) APDU according to Le |
| SW1-SW2 | Status bytes |
NOTE – The status bytes belong to the ENVELOPE command. Status bytes of a command transmitted in the data field of the ENVELOPE command may be found in the data field of the ENVELOPE response.
The following specific error conditions may occur.
SW1=’67’ with SW2=
