I'm trying to change UART0_Tx configuration from PTB1 to PTA3 external pin, setting the SIM_PINSEL register:
|SIM->PINSEL |= (SIM_PINSEL_UART0PS_MASK | SIM_PINSEL_IICPS_MASK) ;|
I correctly read the external output UART0 signal on PTB1 pin but I'm not able to read the same output on PTA3. Do you know if it's necessary to set some other registers to obtain the output data on the other pin? Thank you.
