To write data:
1.
Query TDRD flag (buffer ready?) and write the number of bytes to send
(copied from SIO register to transmit FIFO) to TBUF_CNT.
2.
Read the available data space left in TBUF_ST (if the buffer can hold
more bytes than are to be transmitted) and number of bytes written to
transmit buffer in TBUF_CNT (if more data are to be transmitted than fit
in the buffer).
3.
Write character to SIO_DATA_REGISTER, beginning at char 0.
4.
To output more characters, repeat from step 1.
