Infrared Serial Communications
13.11.3 SCI Control Register 3
Data Sheet

Address:
Infrared Serial Communications Interface Module (IRSCI)
SCI control register 3:
R8 — Received Bit 8
T8 — Transmitted Bit 8
Reset:
Read:
Write:
•
•
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.
Stores the ninth SCI data bit received and the ninth SCI data bit to
be transmitted
