Hi Team,
In datasheet, it can set the Forward Channel GPIO can be set: 0, 1,2,and 4 as the following picture.
For the application, the 4 forward channel GPIOs will be enabled to transmit I2S signals but it will just use 3 GPIO pins for BCLK, WS and SD as following. Does it mean that the remain GPIO cannot be set to back channel?
Best regards,
Albert Lee.
