A method and apparatus in which a radio frequency transceiver is controlled via a plurality of connectors including providing control information for changing a mode of operation of the receiver. The modes can be transmit and receive modes, and the connectors can be configured to perform various functions depending on the mode of operation. Control signals, time critical control signals, and other types of signals may be received at one or more of the connectors in the different modes of operation. The functions may control a power amplifier of a transmitter portion of the transceiver, read/write data from/to registers of the transceiver, and/or other functions.

Interface for controlling a transceiver

An interface between base band circuitry and RF transceiver circuitry, particularly relating to the Bluetooth standard. The interface has a plurality of connectors (DBus) for controlling the RF transceiver circuitry including providing control information for changing the mode of operation of the transceiver, said modes including a transmit mode and a receive mode; at least first and second further connectors (RFBus) wherein in the transmit mode, one of said first and second connectors supplies data to the transceiver and the other is operable to perform a first function such as controlling the power amplifier in the RF circuitry and wherein, in the receive mode, one of said first and second connectors receives data from said RF module and the other is operable to perform a second function different from the first function.

Interface

The invention relates to a method for interrupting an idle state of a communication unit in a communication system, especially in a radio communication system. To keep the response time of a communication unit operating in a standby mode as short as possible following a user input, it is provided according to the invention that, in response to an interrupt request, the time still remaining to the next activation is reduced to a time which is sufficient for preparing the activation if the time still remaining is greater than a predetermined time.
