POWER UP AND DOWN CONTROL IN HARDWARE MODE
In hardware mode the MCLK, BCLK and MUTE
or down, and this is summarised in Figure 25 below.
Figure 25 Hardware Power Sequence Diagram
Power Up
To power up the device, start MCLK and BCLK and set MUTE
Power Down to Standby
To power down to a standby state leaving the charge pump running, either set the MUTE
stop BCLK. MCLK must continue to run in this situation. The device will automatically mute and power
down quietly in either case.
Power Off
To power down the device completely, stop MCLK at any time. It is recommended that the device is
placed into standby mode as described above before stopping MCLK to allow a quiet shutdown.
