=== 9.4.2.1 Constrained Transfers With No Chaining ===

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

== Notation ==

Le = CAD expected length. 

Lr = Applet response length set via **setOutgoingLength** method. 

The transport protocol sequence shall not use block chaining. Specifically, the M-bit (more data bit) shall not be set in the PCB of the I-blocks during the transfers (ISO/IEC 7816-3:2004). The entire outgoing data (Lr bytes) shall be transferred in one I-block.  

If the applet aborts early and sends less than Lr bytes, zeros shall be sent instead to complete the remaining length of the block. 

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