Max SAI TXD output in IMX8MN

[takayuki_ishii]

Hello community,

Can SAI's TX be set to a maximum of only 9 outputs?

In IMX8M Nano, it have 5x SAI module and Tx/Rx are following.

Five external SAI (synchronous audio interface) modules supporting I2S, AC97,
TDM, codec/DSP and DSD interfaces, including one SAI with 4 TX and 4 RX lanes,
two SAI with 2 TX and 2 RX lanes, and two SAI with 1 TX and 1 RX lanes.

It seems that total TX lanes are 10.( 4x1 + 2x2  + 1x2)

But SAI2_TXD0 and SAI5_TXD3 can allocate only same output pin.

Can SAI's TX be set to a maximum of only 9 outputs?

Best regards,

Ishii.

Hi @takayuki_ishii,

Hope you are doing well.

Pin No. AC22 can be configured either as SAI2_TXD0 or SAI5_TX_DATA3. So, maximum 9 output data channels can be used for SAI TX.

Thanks & Regards,
