Shutdown Sequence
Enter:
1.
Ensure I2S clocks have been stable and valid for at least 50ms.
2.
Write 0x40 to register 0x05.
3.
Wait at least 1ms+1.3*Tstop (where Tstop is specified by register 0x1A).
4.
Once in shutdown, stable clocks are not required while device remains idle.
5.
If desired, reconfigure by ensuring that clocks have been stable and valid for at least 50ms before
returning to step 4 of initialization sequence.
Exit:
1.
Ensure I2S clocks have been stable and valid for at least 50ms.
2.
Write 0x00 to register 0x05 (exit shutdown command may not be serviced for as much as 240ms
after trim following AVDD/DVDD powerup ramp).
3.
Wait at least 1ms+1.3*Tstart (where Tstart is specified by register 0x1A).
4.
Proceed with normal operation.
Powerdown Sequence
Use the following sequence to powerdown the device and its supplies:
1.
If time permits, enter shutdown (sequence defined above); else, in case of sudden power loss,
assert PDN = 0 and wait at least 2ms.
2.
Assert RESET = 0.
3.
Drive digital inputs low and ramp down PVDD supply as follows:
Drive all digital inputs low after RESET has been low for at least 2s.
Ramp down PVDD while ensuring that it remains above 8V until RESET has been low for at
least 2s.
4.
Ramp down AVDD/DVDD while ensuring that it remains above 3V until PVDD is below 6V and
that it is never more than 2.5V below the digital inputs.
