ed in NAAS interrupt handler to support data
              received less than FIFO size prior to NAAS interrupt.
              Fixed for CR590212.
2.04a sdm  07/22/11 Added IsSlaveSetAckOff flag to the instance structure.
              This flag is set when the Slave has set the Ack Off in the
              RecvSlaveData function (<a class="el" href="xiic__slave_8c.html">xiic_slave.c</a>) and
              is cleared in the NotAddrAsSlaveHandler (<a class="el" href="xiic__slave_8c.html">xiic_slave.c</a>)
