Hi Yoshiki-san,

For the start up of TAS5805, steps below are needed to be followed:

1. PVDD/DVDD are powered --- start;

2. PDN is pulled high              --- no time requirement from step 1 to step 2;

3. Delay 5ms                          --- 5ms

4. I2S is given and kept stable 

5. I2C initialization begin        --- no time requirements from step 4 to step 5; 

    note: as to step 5, the time consumption depends on the lines of i2C commands. Further a 5ms delay in integrated in the commands that can be found in dumped .h file.

6. Last l2C commands in step 5 will bring TAS5805 from HIz to play. There is a ramp up time during this step. You can calculate it by:ramp up time(256/LRCLK)

Alix Wan.
