The DAP has two groups of commands. One set is for configuration and is intended for use only during
initialization. The other set has built-in click and pop protection and may be used during normal operation while
audio is streaming. The following supported command sequences illustrate how to initialize, operate, and
shutdown the device.
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 PVCC/AVCC supply as follows:
Drive RESET=0, PDN=1, HIZ=1, and other digital inputs to their desired state, observing
absolute maximum ratings relative to AVDD/DVDD. Provide stable and valid I2S clocks (MCLK,
LRCLK, and SCLK). Wait at least 100us, drive RESET=1, and wait at least another 13.5ms.
Ramp up PVCC/AVCC to at least 10V while ensuring it remains below 7.5V for at least 100us
after AVDD/DVDD reaches 3V. Then wait at least another 10us.
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):
Biquads (0x29-36)
DRC parameters (0x3A-3C, 0x40-42, and 0x46)
Bank select (0x50)
5. Configure remaining registers
6. Exit shutdown (sequence defined below).
Normal Operation
The following are the only events supported during normal operation:
(a) Writes to master/channel volume registers
(b) Writes to soft mute register
(c) Enter and exit shutdown (sequence defined below)
(d) Clock errors and rate changes
Note: Events (c) and (d) are not supported for 240ms+1.3 × tstart after trim following AVDD/DVDD powerup
ramp (where tstart is specified by register 0x1A).
