nrf5340 i2s read frame using ECHO sample

Hi,

I have now sync the transmit of  nrf IC to communicate with tas2781 audio amplifier. at this moment I'm working on the feedback measurement read of the I/V measurement data of the tas2781 transmitted over the SDIN data line of the nrf5340.

as per I2s read below (from i2s echo sample) the mem_block variable should contain the 2x half frame data which is good, but just wondering is if their is a clean way in i2s_read function to just populate the mem_block variable with the left frame data and disregard the right frame so I dont need to process the buffer just segregating LR channels?

thanks you in advance in taking time to respond to my inquiries. So far the support I get from this site in unmatched..
