Description of the data path
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 buf-
fer).
3. Write character to SIO_DATA_REGISTER, beginning at char 0.
4. To output more characters, repeat from step 1.
