I am using FRDMKE06z Board and UART1 and UART2 is tested and working fine for LIN Protocol.
Right now for UART0 when I check at pin A2 and A3 I have tested and no transmission is fount to be happening.
SIM->PINSEL |= SIM_PINSEL_UART0PS_MASK;
I am seeing the register PINSEL is getting updated.
When checked with Oscilloscope I am getting Tx is always low.
Please let me know anything else i have to implement for using UART0.
