I'm wondering if there is an error in the MK22DX128VMC5datasheet: https://www.nxp.com/docs/en/data-sheet/K22P121M50SF4.pdf
Section 8.1 shows signals I2S0_TXD1 available on PTC0 and I2S0_RXD1 on PTC11. However section 184.108.40.206 of the reference manual (https://www.nxp.com/docs/en/reference-manual/K22P121M50SF4RM.pdf ) says there is only one TX data line (I2S0_TXD0 I assume) and one RX data line (I2S0-RXD0?). Also, I am told only one data path seems to be supported in Processor Expert and MCUXpresso for this particular MCU.
I'm also wondering if the same problem exists in MK21DX128AVMC5.
