3.4 PCM Interface PCM application PN6280 provides a digital audio interface (PCM) that can be used as a PCM master device to transmit digital voice signals. PN6280 only acts as a master device. PCM sync, PCM CLK are as output pins and PCM sync output 16kHz synchronization signals, the PCM data support 8-bit or 16 bit data format.
Page 21: Iic Interface
PN6280_Hardware Design 3.5 IIC Interface PN6280 module does not have a dedicated IIC interface. If you need to use the IIC interface for communication, you should use the GPIO port to simulate the IIC interface, and it is recommended to use an external pull-up resistor of 4.7K by VIO18.
