R8 — Received Bit 8
R8 is the ninth data bit received when the SCI is configured for 9-bit
data format (M = 1).
T8 — Transmit Bit 8
T8 is the ninth data bit transmitted when the SCI is configured for 9-bit
data format (M = 1).
R7–R0 — Received bits seven through zero for 9-bit or 8-bit data
formats
T7–T0 — Transmit bits seven through zero for 9-bit or 8-bit formats
NOTE:
If the value of T8 is the same as in the previous transmission, T8 does
not have to be rewritten. The same value is transmitted until T8 is
rewritten.
