M — Mode (select character format)
WAKE — Wake-up by address mark/idle
ILT — Idle line type
This bit determines which of two types of idle line detection method is used by the SCI receiver.
In short mode the stop bit and any bits that were ones before the stop bit will be considered as
part of that string of ones, possibly resulting in erroneous or premature detection of an idle line
condition. In long mode the SCI system does not begin counting ones until a stop bit is received.
PE — Parity enable
PT — Parity type

Start bit, 9 data bits, 1 stop bit.
Start bit, 8 data bits, 1 stop bit.
Wake-up by address mark (most significant data bit set).
Wake-up by IDLE line recognition.
Long (SCI counts ones only after stop bit).
Short (SCI counts consecutive ones after start bit).
Parity enabled.
Parity disabled.
Parity odd (an odd number of ones causes parity bit to be zero, an
even number of ones causes parity bit to be one).
Parity even (an even number of ones causes parity bit to be zero, an
odd number of ones causes parity bit to be one).
