impedance input.
For a read operation, the Bluetooth spi_txd is put in high impedance state after the reception of the ad-
dress.
Note that this feature works independently of the SPI mode, supporting other combinations.
In this case, the devices are connected as described in the figure below.

8.2.2 Feature description: 32 bit SPI
One application is a Bluetooth stereo headset. In this application, the audio samples are received from the
emitter through the air using the Bluetooth baseband with ACL packets. The samples are decoded by the
embedded ARM CPU (the samples were encoded, for compression, in SBC or MP3 format) and then sent
to a stereo codec though the SPI interface. The application is described in the figure below.
Figure 7.
To support this application, the data size is 32 bits. The 32 bits support is implemented for both transmit
and receive.
8.3 I2C Interface
Used to access I2C peripherals.
The interface is a fast master I2C; it has full control of the interface at all times. I2C slave functionality is
not supported.
