Figure 16.17 shows a sample flowchart for serial data transmission. Even if the TDRE flag is
cleared to 0, transmission will not start while a receive error flag (ORER, FER, or PER) is set to 1.
Make sure to clear the receive error flags to 0 before starting transmission. Note that clearing the
RE bit to 0 does not clear the receive error flags.
