K66 - SAI - 2 data lines

[Argail]

I'm looking for some clarification on how the SAI module works on the K66 MCU.

There is only one SAI on this device but the datasheet says there is 2 Tx data lines and 2 Rx data lines. Does this means I may connect one GSM module with I2S interface and one monaural I2S audio codec on the same MCU and at the same time?

Hi Argail,

There is only one TX_BCLK and one RT_BCLK. If you have two devices and both need RX and TX, they have to share same TX_BCLK and RT_BLCK. Their data is independent.
