I'm using the MC9S08DZ60.
If I connect the SCI2 TX and RX pins to the same line, enable receiver and transmitter, enable Transmission complete interrupt and enable Receiver Interrupt, which interrupt will be served first when sending data? The transmission complete interrupt or the receiver interrupt?
