CHAPTER 15 ASYNCHRONOUS SERIAL INTERFACE A (UARTA)
This interrupt occurs upon transfer of receive data from the receive
shift register to receive data register after serial transfer completion,
in the reception enabled status.
This interrupt occurs upon transfer of transmit data from the
transmit data register to the transmit shift register in the
transmission enabled status.
