Figure 56. Power Loss Sequence
Initialization Sequence
Use the following sequence to power-up and initialize the device:
1.
Hold all digital inputs low and ramp up AVDD/DVDD to at least 3V.
2.
Initialize digital inputs and PVDD supply as follows:
Drive RESET = 0, PDN = 1, and other digital inputs to their desired state while ensuring that
all are never more than 2.5V above AVDD/DVDD. Wait at least 100s, drive RESET = 1, and
wait at least another 13.5ms.
Ramp up PVDD to at least 8V while ensuring that it remains below 6V for at least 100s after
AVDD/DVDD reaches 3V. Then wait at least another 10s.
3.
Trim oscillator (write 0x00 to register 0x1B) and wait at least 50ms.
4.
Configure the DAP via I2C (see Users's Guide for typical values).
5.
Configure remaining registers.
6.
Exit shutdown (sequence defined below).
Normal Operation
The following are the only events supported during normal operation:
1.
Writes to master/channel volume registers.
2.
Writes to soft mute register.
3.
Enter and exit shutdown (sequence defined below).
4.
Clock errors and rate changes.
Note: Events 3 and 4 are not supported for 240ms+1.3*Tstart after trim following AVDD/DVDD powerup
ramp (where Tstart is specified by register 0x1A).
