Part Number: TAS6424L-Q1

Hi,

We found register 0X13 bit5 is "1" means VDD POR occurred.

Is possible root cause for VDD POR?

So far, our VDD pin voltage around 3.5V.

Is possible cause VDD POR?

Warm Regards,
Lin

    Lin,

    VDD POR means a POR event happened, can be below two case:

    1. The first initial power up POR, it is normal behavior, just clear it during first time register configuration.

    2. POR happen during normal working. that means something wrong may happened to VDD power, some registers may be not correct, host processor need to re-configure all the registers.
