Can clock signal be shared across DAIs in ADSP-21568/21564?
Can clock signal be shared across DAIs in ADSP-21568/21564?
DAI allows few signals to be interconnected across DAI units, known as cross mode connections. This cross mode connection can be used to share a clock signal across DAIs. DAI0_PIN03/ DAI0_PIN05 and DAI1_PIN03/ DAI1_PIN05 can be used to share clock signal across DAI. When DAI0_PIN03/ DAI0_PIN05 is configured as input clock pin then this clock signal is available in Group A of both DAIs. Peripherals routed through DAI0 like PCG A and SPORT 0A can use DAI0_PB03_O/ DAI0_PB05_O as the input clock signal. Peripherals routed through DAI1 like PCG C, SPORT 4A can use DAI1_CRS_PB03/ DAI1_CRS_PB05 as the input clock signal.
