摘要： Different scan modes are provided for Bluetooth devices. In at least some embodiments, a narrowband scanning mode looks for signal energy on individual transmission frequencies at a time. By looking for signal energy rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A midband scanning mode looks for signal energy across multiple different frequencies at a time. Again, by looking for signal energy across multiple different frequencies rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A wideband scanning mode looks for signal energies across all relevant frequencies at a time. At least some embodiments enable a Bluetooth device to switch between scanning modes.

摘要： Method and apparatus for communicating numeric data between first and second circuits incorporating a controller communicatively coupled to the first circuit to receive the numeric data, and an accumulator communicatively coupled to the second circuit and the controller, the accumulator comprising accumulator logic managing reference data, the controller being responsive to the numeric data selectively causing the accumulator logic to increment or decrement the reference data to match the numeric data. The accumulator will notify the second circuit of the so-updated reference data. In one embodiment, three signal lines (UP, DN, CLK) are used by the controller to direct the accumulator to increment, decrement, reset or hold the reference data. In another embodiment, only two signal lines are used at the expense of reset complexity.

摘要： A communication apparatus comprises accumulator logic managing reference data. First, second, and third inputs are communicatively coupled to the accumulator logic and capable of receiving first, second, and third signals respectively. The first and second signals express one of a true and a false state. The accumulator logic increments the reference data when the accumulator logic receives the third signal while the first signal expresses the true state. The accumulator logic decrements the reference data when the accumulator logic receives the third signal while the second signal expresses the true state.

摘要： A wireless network device having active and inactive modes comprises a clock generating module that generates a first clock signal having a first clock rate. A voltage supply module generates a first voltage level and a second voltage level that is less than the first voltage level. A first digital module receives the first clock rate and the first voltage level during the active mode, receives the second voltage level during the inactive mode and does not receive the first clock signal during the inactive mode. A first analog module communicates with the voltage supply module and has reduced current consumption during the inactive mode.
