When the no chaining mode of output transfer is requested by the applet by calling the setOutgoingNoChaining method, the following protocol sequence shall be followed:

When the no chaining mode is used (that is, after the invocation of the setOutgoingNoChaining method), calls to the waitExtension method shall throw an APDUException with reason code ILLEGAL_USE.

Le = CAD expected length.

Lr = Applet response length set via setOutgoingLength method.

= the protocol byte equal to the incoming header INS byte, which indicates that all data bytes will be transferred next.

= the protocol byte that is the complement of the incoming header INS byte, which indicates that 1 data byte will be transferred next.

= the response status bytes as in ISO7816-4.

1. The card sends Lr bytes of output data using the standard T=0 or procedure byte mechanism.

2. The card sends completion status on completion of the Applet.process method.

1. The card sends completion status bytes

2. The CAD sends GET RESPONSE command with Le = Lr.

3. The card sends Lr bytes of output data using the standard T=0 or procedure byte mechanism.

4. The card sends completion status on completion of the Applet.process method.

1. The card sends Le bytes of output data using the standard T=0 or procedure byte mechanism.

2. The card sends completion status bytes

3. The CAD sends GET RESPONSE command with new Le ⇐ Lr.

4. The card sends (new) Le bytes of output data using the standard T=0 or procedure byte mechanism.

5. Repeat steps 2-4 as necessary to send the remaining output data bytes (Lr) as required.

6. The card sends completion status on completion of the Applet.process method.

In Case 4, Le is determined after the following initial exchange:

1. The card sends

2. The CAD sends GET RESPONSE command with Le ⇐ Lr.

The rest of the protocol sequence is identical to CASE 2 described above.

If the applet aborts early and sends less than Le bytes, zeros shall be sent instead to fill out the length of the transfer expected by the CAD.
