TRF7970A: How to clear ISO_7816_4_CONNECTION_READ_FAIL

Hi All,

I eventually get into a state where ISO_7816_4_processReceivedData() has g_eISO7816CommStatus == ISO_7816_4_CONNECTION_READ_FAIL

Looking at the switch statement handling this case:

case ISO_7816_4_CONNECTION_READ_FAIL:
// Wait until the user clears the state by using the check Response AP
break;

How does the user "clear this state by using the check Response AP"??? 

Regards,
Robert
