摘要： A system includes a communication apparatus coupled to a test subsystem through a converter. The test subsystem may be configured to initiate an audio test of the communication apparatus and receive in response a set of audio test data at a predetermined constant data rate. The communication apparatus may be configured to enable output of audio test data during inactive periods of operation of an RF circuit of the communication apparatus and to disable output of audio test data during active periods of operation of the RF circuit. The converter may be configured to receive the set of audio test data from the communication apparatus and provide the set of audio test data to the test subsystem at the predetermined constant data rate during the active and the inactive periods of operation of the RF circuit.

摘要： A method of operating a radio-frequency (RF) circuitry and a signal-processing circuitry in a mobile telephone apparatus includes at least partially disabling the signal-processing circuitry while transmitting or receiving signals. In one example, a processor is efficiently disabled by generating and servicing an interrupt of relatively high priority. One advantage of this example is that preexisting, legacy code can be maintained, while still achieving the desired objectives. The processor can be enabled by generating and servicing a second high priority interrupt.

摘要： A communication apparatus includes a radio frequency circuit that operates on a radio frequency signal and a digital processing circuit coupled to the radio frequency circuit. The digital processing circuit includes a plurality of bus masters coupled to a shared bus. A bus arbiter is provided for arbitrating between requests to access the bus by a first bus master and one or more other bus masters. Accesses by the one or more other bus masters to the bus are restricted in response to a signal indicative of a change in a mode of operation of the RF circuit. In one particular implementation, a communication apparatus employs time domain isolation wherein the digital processing circuit may be placed in a shutdown mode when the radio frequency circuit is active.

摘要： A communication apparatus includes a radio frequency circuit that operates on a radio frequency signal and a digital processing circuit coupled to the radio frequency circuit. The digital processing circuit includes a first timing circuit that provides timed signals to control timing of system operations during an active mode of operation of the digital processing circuit, and a second timing circuit that provides timing signals to control timing of system operations during an active mode of operation of the radio frequency circuit. In one particular embodiment, at least a portion of the first timing circuit is disabled when the radio frequency circuit is active (receiving and/or transmitting).

摘要： Apparatus and methods for scanning a keypad of a communications device in a manner that tends to minimize interference with transceiver operation, such as a RF transceiver. In one embodiment, a controller receives a periodic signal of the communications device and provides a scan signal to cause the keypad to be scanned. In a sleep mode a keypad scan is performed only subsequent to a keypad activation. However, if the communications device is in use a keypad scan is performed once per frame at predetermined intervals, in one embodiment.
