Hi, can I config two groups of UART by FlexIO?
Yes, you can configure 2x UART by FlexIO.
If we check chapter "52.1.1 FlexIO Configuration" in the RM rev 9. we can see that there are 4x Timer, 4x Shifter, and 8x Pin.
For the one UART receive we need 1x shifter and 1x timer and for the transmit, we need 1x shifter and 1x timer.
So, we can configure max 2x UART by FlexIO.
I hope it helps.
