The DAI has a dedicated interrupt controller that generates interrupts for audio events. These interrupts are mapped to two priority levels (high and low) in the SHARC core’s primary interrupt system. The system can handle up to 32 different audio-related interrupt sources, which are OR'ed together into one interrupt signal for the core to process.
The attached example configures DAI0 to trigger an Interrupt on the Rising Edge. To test the interrupt functionality, DAI0_PIN01 is externally connected to DAI0_PIN02. This configuration allows the interrupt to be activated by toggling the state of the DAI pin.
