Abstract
A method of communicating with a secure element (SE) is described. The method includes transmitting successive RSET frames from a single wire protocol (SWP) interface to an SE, the successive RSET frames including RSET frame retransmissions. The method also includes counting a number of successive RSET frame retransmissions due to a timer expiring. The method further includes generating a firmware interrupt in response to determining that the count has reached a threshold. The method additionally includes deactivating the SWP interface based on the firmware interrupt.
