SCCR2 — SCI Control Register 2
T8 — Transmit Data bit 8
M — Mode (Select Character Format)
WAKE — Wake-up by Address Mark/Idle
7.6.3 Serial Communications Control Register 2 (SCCR2)
TIE — Transmit Interrupt Enable
TCIE — Transmit Complete Interrupt Enable
RIE — Receiver Interrupt Enable
ILIE — Idle Line Interrupt Enable
TE — Transmitter Enable
RE — Receiver Enable
RWU — Receiver Wake-Up Control

RESET:
If M bit is set, T8 stores ninth bit in transmit data character.
The SCCR2 register provides the control bits that enable or disable individual SCI
functions.
When TE goes from zero to one, one unit of idle character time (logic one) is queued
as a preamble.
0 = Start bit, 8 data bits, 1 stop bit
1 = Start bit, 9 data bits, 1 stop bit
0 = Wake-up by IDLE line recognition
1 = Wake-up by address mark (most significant data bit set)
0 = TDRE interrupts disabled
1 = SCI interrupt requested when TDRE status flag is set
0 = TC interrupts disabled
1 = SCI interrupt requested when TC status flag is set
0 = RDRF and OR interrupts disabled
1 = SCI interrupt requested when RDRF flag or the OR status flag is set
0 = IDLE interrupts disabled
1 = SCI interrupt requested when IDLE status flag is set
0 = Transmitter disabled
1 = Transmitter enabled
0 = Receiver disabled
1 = Receiver enabled
0 = Normal SCI receiver
1 = Wake-up enabled and receiver interrupts inhibited
