We need to use the UART functionality on pin PTE22 and PTE23 i.e.UART2_TX and UART2_RX in MKL36Z256VLH4. The data transmission is working as expected, but UART reception is not working. I have done following setting,
set the value of MUX to100 to use ALT4 in register PORTE_PCR23,
RIE, RE flags set to 1 in register UART2_C2
clear RDMAS in register UART2_C4
when data is sent to microcontroller, value of UART_D does not change, also RDRF in register UART2_C2 remains 0. Also no interrupt for reception is generated. I guess the pin is not configured correctly. am I missing something?
Thanks in Advance.
