I'm new to the Kinetis K64 series of microcontrollers. I would like to detect whether the UART receiver line is idle or active. I'm currently using Processor Expert  AS1_ReceiveBlock(), UART1 to receive incoming serial data and it works great. I know that UART1_S2 is the status register i need to work with.  But how do i access the RAF field ?
