5.8.2 Serial Communications Control Register 1 (SCCR1)
The serial communications control register 1 (SCCR1) provides the control bits which:
(1) determine the word length, and (2) select the method used for the wake-up feature.
R8 — Receive Data Bit 8
If the M bit is set, this bit provides a storage location for the ninth bit in the receive data
character.
T8 —Transmit Data Bit 8
If the M bit is set, this bit provides a storage location for the ninth bit in the transmit
data character. It is not necessary to write to this bit for every character transmitted,
only when the sense is to be different than that for the previous character.
Bit 5 — Not Implemented
This bit always reads zero.
M — SCI Character Length
0 = 1 start bit, 8 data bits, 1 stop bit
1 = 1 start bit, 9 data bits, 1 stop bit
WAKE — Wake Up Method Select
0 = Idle Line
1 = Address Mark
Bits 2-0 — Not Implemented
These bits always read zero.
5.8.3 Serial Communications Control Register 2 (SCCR2)
The serial communications control register 2 (SCCR2) provides the control bits which
enable/disable individual SCI functions.
TIE — Transmit Interrupt Enable
0 = TDRE interrupts disabled
1 = SCI interrupt if TDRE = 1
