        Hi,

        I don’t think my previous ticket was sent, I send it with my account.

        I’m using IDC777 with a MCU and a DSP and those components work with 1V8 signals.

        I understand that the module’s VDD_PADS pin changes the working voltage of IOs.

        Could you confirm that if I put 1.8V on VDD_PADS pin, the UART and PCM will work with 1.8V levels ?

        Regards,
