Suspend and Resume Sequence
The PCM2900/2902 enters the suspend state after it sees a constant idle state on the USB bus, approximately
5 ms. While the PCM2900/2902 enters the suspend state, SSPND flag (pin 28) is asserted. The
PCM2900/2902 wakes up immediately when detecting the non-idle state on the USB bus.
