The PCM2912A enters a suspend state when it sees a constant idle state on the <strong>USB</strong> bus after approximately 5<br />
ms. When the PCM2912A enters the suspend state, the SSPND flag (pin 29) is asserted. The PCM2912A wakes<br />
up immediately after detecting the non-idle state on the <strong>USB</strong> bus. Figure 36 illustrates these actions.<br />
