Figure 13.17 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 that the receive error flags are cleared to 0 before starting transmission. Note that
clearing the RE bit to 0 does not clear the receive error flags.
