Abstract
A portable mobile communication device () has a mobile host processor () permanently installed in the portable mobile communication device () and a near field communication circuit () comprising a non-volatile memory (). Configuration data is maintained in the non-volatile memory () of the near field communication circuit (), for control of communication dependent on the configuration data. Prior to communication between the near field communication circuit () and the mobile host processor () a session identity value is tested. If the session identity value does not match a reference value, at least part of the configuration data for the communication channel is initialized, after which the session identity value and the reference value are equalized after setting up the configuration data. If the session identity value matches the reference value, the mobile host processor () proceeds with communication without said initialization. In this way wear of the non-volatile memory due to superfluous initialization after unintentional power downs or resets of the mobile host processor () is prevented.
