I want to create I2S connection between FRDM K64F to CS4272 Codec chip by Cirrus Logic. The K64F has 7 ports for I2S while the chip only has 5, currently this is the setup, is this right?
FRDM-K64F CS4272
RXD SDOUT
RX_FS (MUX) LRCK
USB_SOF_OUT ???
RX_BCLK (MUX)SCLK
MCLK MCLK
TXD SDIN
TX_FS (MUX) LRCK
TX_BCLK (MUX)SCLK
Thanks,
