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 IRSCDR 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 IRSCDR 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.
Reset clears ORIE.
This read/write bit enables SCI error CPU interrupt requests generated by the noise error bit, NE.
Reset clears NEIE.
This read/write bit enables SCI error CPU interrupt requests generated by the framing error bit, FE.
Reset clears FEIE.
This read/write bit enables SCI error CPU interrupt
requests generated by the parity error bit, PE. (See
PEIE.
