Chapter 13 Serial Communications Interface (S12SCIV2) Block Description
13.4.4
13.4.4.1
The SCI receiver can accommodate either 8-bit or 9-bit data characters. The state of the M bit in SCI
control register 1 (SCICR1) determines the length of data characters. When receiving 9-bit data, bit R8 in
SCI data register high (SCIDRH) is the ninth bit (bit 8).

When queueing an idle character, return the TE bit to logic 1 before the stop
bit of the current frame shifts out through the Tx output signal. Setting TE
after the stop bit appears on Tx output signal causes data previously written
to the SCI data register to be lost. Toggle the TE bit for a queued idle
character while the TDRE flag is set and immediately before writing the
next byte to the SCI data register.
If the TE bit is clear and the transmission is complete, the SCI is not the
master of the TXD pin
