An Interrupt is activated by enabling this device (offset 0x30), setting this register to a non-
zero value and setting any combination of bits 0-4 in the corresponding UART IER and the
occurrence of the corresponding UART event (i.e. Modem Status Change, Receiver Line
Error Condition, Transmit Data Request, Receiver Data Available or Receiver Time Out) and
setting the OUT2 bit in the MCR.
