    Hello,

    When data received on Rx pin and shifted into SCIRXSHF is transferred to SCIRD register, RXRDY flag is set and interrupt is generated ( if RX Interrupt is enabled ). And in the ISR data is read. To connect SCI port to a PC you will need UART-->USB adapter ( I/O voltage is 3.3V ). When PC send data to SCI port, interrupt will be generated and in ISR you can read data. Off course you can use SCI/LIN (in the same way as in your code) because it is connected to U7 which acts as JTAG emulator and exposes UART to a PC. CCS has integrated Terminal which can be used for tests. You can activate Continuous refresh and watch RX_Text in Expression window. Pressing button on keyboard (while in terminal window) a character will be received in RX_Text.
