Other Parts Discussed in Thread: , TAS2555
Our customer is using TAS2560 with Snapdragon, MCK input is 9.6MHz, Fs is 48KHz and register setting is following.
Power supply is 5V adopter which is included in EVM box.
At 1st time music playback works well, after that BCK and WCLK are stopped from DSP then second trial of playback, sound does not come out even BCK and WCLK are present.
"Power Up Control 2" showed 0x05=1, PWR_ERR is detected.
"Interrupt Detected 1 Field Descriptions" showed 0x26=2a. It is ASI CLK error1, Brownout error and SAR complete error.
Because of BCK and WCLK are stopped.
Here are questions.
1.To recover this condition, should we assert soft reset and reload all of register when move to playback everytime?
We had tried "CLK_ERR_1 Register" 0x21 to 82, It will "Reload defaults on restart",but not improved.
2.What is threshold voltage value to detect PWR_ERR and Brownout? How can we ignore those flags?
0x04 Class G or H setting did not make difference.
