Hi,
I have the following I2S0 signals connections to a stereo CODEC.
I2S0_TX_MCLK connected to the CODEC
I2S0_TX_SCK connected to the CODEC
I2S0_TXWS connected to the CODEC
I2S0_TX_SDA connected to the DAC data input of the CODEC
I2S0_RX_SDA connected to the ADC data output of the CODEC
Because of this configuration, I decided to configure I2S0 transmitter as MASTER and I2S0 receiver in 4 wire mode (slave mode).
I then enable the RX interrupt for I2S0.
In this configuration I don't receive any RX interrupts !
Do you have any idea why ?
Is it some kind of limitation of the 4 wire mode ?
it doesn't really make any sense to me.
Thanks.
Vince
