Received Bit 8 — R8 is the ninth data bit received when the SCI is configured for 9-bit data format (M = 1).
Transmit Bit 8 — T8 is the ninth data bit transmitted when the SCI is configured for 9-bit data format (M = 1).
Received Bits — Received bits seven through zero for 9-bit or 8-bit data formats
Transmit Bits — Transmit bits seven through zero for 9-bit or 8-bit formats

In 8-bit data format, only SCI data register low (SCIDRL) needs to be
accessed.
When transmitting in 9-bit data format and using 8-bit write instructions,
write first to SCI data register high (SCIDRH), then SCIDRL.
If the value of T8 is the same as in the previous transmission, T8 does not
