In an RF communication control system comprising an RF control circuit unit including a plurality of RF control elements for executing the process of transmitting and receiving an RF signal and a baseband circuit unit for executing various digital processes on the data contained in the RF signal sent out from the RF control circuit unit, one of a plurality of the RF control elements of the RF control circuit unit being connected selectively to the baseband circuit unit, the setting parameter holder of the baseband circuit unit holding the setting parameter for each of the RF control elements;
- a computer-readable storage medium for storing a computer program whereby when the RF control element connected to the baseband circuit unit is switched to a second RF control element, the setting parameter to be used for the second RF control element is determined based on the setting information supplied from an external source for the second RF control element, and the setting parameter corresponding to the second RF control element is selected based on the result of determining the setting parameter and sent out to the second RF control element.
