The latter two functions will block until the master has initiated and finished a transaction, causing the queued data to be sent and received.

WebMaster/Slave Modes. This SPI driver functions in both SPI master and SPI slave modes. Logically, the implementation is identical, however the difference between these two modes is driven by hardware. As a SPI master, the peripheral is in control of the clock signal and therefore will commence communications to the SPI slave immediately. WebNxH3670 SPI slave interface, it has an SPI master interface. In the dongle configuration, the host controller converts the audio from USB to I2S. The host controller is the I2S master while the NxH3670 is the I2S slave. In addition, the host controller has an I2C master interface which can be connected to the codec or any external I2C device. get the approval
