11.8.3 SCI Control Register 3
SCI control register 3:

When the SCI is receiving 9-bit characters, R8 is the read-only ninth bit (bit 8) of the received
character. R8 is received at the same time that the SCDR receives the other 8 bits.
When the SCI is receiving 8-bit characters, R8 is a copy of the eighth bit (bit 7). Reset has no effect
on the R8 bit.
When the SCI is transmitting 9-bit characters, T8 is the read/write ninth bit (bit 8) of the transmitted
character. T8 is loaded into the transmit shift register at the same time that the SCDR is loaded into
the transmit shift register. Reset has no effect on the T8 bit.
This read/write bit enables SCI error CPU interrupt requests generated by the receiver overrun bit, OR.
1 = DMA not enabled to service SCI receiver DMA service requests generated by the SCRF bit (SCI
0 = DMA not enabled to service SCI receiver DMA service requests generated by the SCRF bit (SCI
1 = SCTE DMA service requests enabled; SCTE CPU interrupt requests disabled
0 = SCTE DMA service requests disabled; SCTE CPU interrupt requests enabled
1 = SCI error CPU interrupt requests from OR bit enabled
0 = SCI error CPU interrupt requests from OR bit disabled
Stores the ninth SCI data bit received and the ninth SCI data bit to be transmitted
