Fault detection
The following fault conditions are monitored by the circuit:
Short-circuit or high current on VCC
Removing card during transaction
VDD dropping
Overheating.
When one or more of these faults are detected, the circuit
pulls the interrupt line OFF to its active LOW state and a
deactivation sequence is initiated. In the event that the
card is present the interrupt line OFF is set to HIGH state
when the microcontroller has reset the CMDVCC line
HIGH (after completion of the deactivation sequence).
In the event that the card is not present OFF remains
LOW.
