Transmitting Serial Data (Asynchronous Mode): Figure 12.4 shows a sample flowchart for
transmitting serial data. The procedure is as follows (the steps correspond to the numbers in the
flowchart):
1. SCI status check and transmit data write: Read the serial status register (SSR), check that the
2. To continue transmitting serial data: Read the TDRE bit to check whether it is safe to write (if
TDRE bit is 1, then write transmit data in the transmit data register (TDR) and clear TDRE to
0.
it reads 1); if so, write data in TDR, then clear TDRE to 0.
