Table 19 Standby Mode
In STANDBY mode the Control Interface, a small portion of the digital and areas of the analogue
circuitry remain active. The active analogue includes the analogue VMID reference so that the
analogue line inputs, line outputs and headphone outputs remain biased to VMID. This reduces any
audible effects caused by DC glitches when entering or leaving STANDBY mode.
The device can be powered off by writing to the POWEROFF bit of the Power Down register. In
POWEROFF mode the Control Interface and a small portion of the digital remain active. The
analogue VMID reference is disabled.
