Transmitting Serial Data (Synchronous Mode): Figure 15.19 shows a sample flowchart for
transmitting serial data. The procedure for transmitting serial data is:
1. SCI status check and transmit data write: Read the serial status register (SCSSR), check that
2. To continue transmitting serial data: Read the TDRE bit to check whether it is safe to write (if

Note: Numbers in parentheses refer to steps in the preceding procedure description.
the TDRE bit is 1, then write transmit data in the transmit data register (SCTDR) and clear
TDRE to 0.
it reads 1); if so, write data in SCTDR, then clear TDRE to 0.
