time >= TOUR[1:7].
3. Interrupt Identification:
4. RCVR Interrupt trigger level programing:
5. FCR[7] is always 1. Write FCR[7] to 0 has no effect.
6. Transmitter/Receiver Character length programing:
* Irpt_RLS- caused by: Overrun Error or Parity Error or Framing Error or Break Interrupt.
* Irpt_RDA- caused by: Received data >= RCVR trigger level.
* Irpt_TOUT- caused by: RCVR FIFO is non-empty and have not been accessed (Read/write) for the
* Irpt_THRE- caused by: THRE has been set.
* Irpt_MOS- MODEM Status interrupt: Non-implemented.
