WOMS — Wired-OR Mode for SCI Pins (PD1, PD0; See also DWOM bit in SPCR.)
0 = TxD and RxD operate normally
1 = TxD and RxD are open drains if operating as an output
Bit 5 — Not implemented
Always reads zero
M — Mode (Select Character Format)
0 = Start bit, 8 data bits, 1 stop bit
1 = Start bit, 9 data bits, 1 stop bit
WAKE — Wakeup by Address Mark/Idle
0 = Wakeup by IDLE line recognition
1 = Wakeup by address mark (most significant data bit set)
ILT — Idle Line Type
0 = Short (SCI counts consecutive ones after start bit)
1 = Long (SCI counts ones only after stop bit)
PE — Parity Enable
0 = Parity disabled
1 = Parity enabled
PT — Parity Type
0 = Parity even (even number of ones causes parity bit to be zero, odd number of ones causes par-
ity bit to be one)
1 = Parity odd (odd number of ones causes parity bit to be zero, even number of ones causes parity
bit to be one)

TIE — Transmit Interrupt Enable
0 = TDRE interrupts disabled
1 = SCI interrupt requested when TDRE status flag is set
TCIE — Transmit Complete Interrupt Enable
0 = TC interrupts disabled
1 = SCI interrupt requested when TC status flag is set
RIE — Receiver Interrupt Enable
0 = RDRF and OR interrupts disabled
1 = SCI interrupt requested when RDRF flag or the OR status flag is set
ILIE — Idle Line Interrupt Enable
0 = IDLE interrupts disabled
1 = SCI interrupt requested when IDLE status flag is set
TE — Transmitter Enable
0 = Transmitter disabled
1 = Transmitter enabled
