FRDM-K64F I2S peripheral connection

[rahmatdwiputra]

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,
