As long as the host status underflow bit is set, any mailbox reads that arrive when the mailbox is empty, return garbage data.
The host then reads interface registers to determine the type of function that the AR supports. Advanced architecture and protocol techniques save power during sleep, stand-by and active states.
Synthesizer Composite Characteristics for 2. The Atheros logo is a registered trademark of Atheros Communications, Inc.
The Synthesizer can use several Xtals such as It has dstasheet interfaces: System includes external PA. The PCU also handles datasjeet responses to the transmitted frame and reporting the transmission attempt results to the DCU.
Once the DCU gains access to the channel, it passes the frame to the PCU, which manages the final details of sending the frame to the baseband logic. The CPU may continue to be held in reset under some circumstances until its reset is cleared by an external pin or when the host clears a register. AR System Block Diagram. Figure depicts the state transition diagram.
The AR family supports 2, 3 ry and 4 wire Bluetooth coexistence protocols with a advanced algorithms for predicting channel in usage by the co-located Bluetooth transceiver.
The type of host the AR uses depends upon the polarity of some package pins upon system power-up. The AR baseband module BB is the physical layer controller for the If not, an internal regulator can be used. Advanced s architecture and protocol techniques save power ro during sleep, stand-by and active states. After all clocks are stable and running, the resets to all blocks are 1.
For low power states, the polarity of the switch settings are shown in Table This clock is completely independent from those mentioned above and is driven by the external host to communicate with the AR This clock drives the interface logic as well as a few registers which can be accessed by the host. Typically, this DCU is the one associated with beacons. This is done through a dedicated 8-bit bus interface that is controlled through transmit and receive framing signals.
The core has been configured with several clock gating elements which scale down clocks to circuitry that is not changing. An on-chip PLL creates the appropriate clock frequency for digital logic.
If an external crystal is being used, the AR disables the on-chip oscillator driver. All internal clocks are generated from a. All interrupts can be masked by control registers. It has AHB interfaces from three Masters: A 3V level is required to control front-end components like xPA or a switch, which are made of semiconductors requiring 2. A allowing optimal antenna selection on a per. Software configures the AR functions and interfaces. In addition, software may operate the SI in either polling or interrupt mode.
If there are any radio impairments that need to be corrected carrier leak, etc. Figure shows the host interface address map. Decisions on rate and output power are directed by the MAC through the use of transmit data headers. The VMC contains arbiters to serve these three interfaces on a first-come-first-serve basis.
C performance of the AR family. The RF performance, data throughput, and power consumption further improve upon the performance of the AR family. The AR family supports 2, 3. It then begins communicating with this host. This CPU has four interfaces: Absolute maximum ratings are a6002 values beyond which damage to the device can occur.
The others are hardware interrupts for various configurations.

The BB needs this fundamental clock together with several divided versions of it. Receiver Characteristics for 2. There are two major mechanisms for this: All other trademarks are the property of their respective holders.
When the AR is ready to receive commands from the host, it will set the function ready bit. Pin Descriptions This section contains a listing of the signal descriptions see Table for the BGA package pin outs. The baseband programmable gain filter is shared between the 2G and 5G paths. Software must then either resynchronize flow control state dataheet reset the AR to recover.
