-/**
-* An abstract class for Nfc components.
-* This component has two operation modes, sync or async.
-* In sync mode each function call returns only after the command has completed.
-* In async mode each function call returns immediately and the answer will be notified
-* through a callback.
-* The default behavior is sync mode.
-* To enable the async mode ManageI2CGPO(I2C_ANSWER_READY) function must be called.
-* When the component notifies an interrupt user must call {@link ManageEvent} function.
-* Note that passing a parameter other than I2C_ANSWER_READY to ManageI2CGPO initialize the component in sync mode.
