RSRC — Receiver Source
M — Mode (select character format)
WAKE — Wake-up by Address Mark/Idle
ILT — Idle Line Type
When LOOPS = 1, the RSRC bit determines the internal feedback
path for the receiver.
Determines which of two types of idle line detection will be used by
the SCI receiver.
In the short mode, the SCI circuitry begins counting ones in the search
for the idle line condition immediately after the start bit. This means
that the stop bit and any bits that were ones before the stop bit could
be counted in that string of ones, resulting in earlier recognition of an
idle line.

0 = Wake up by IDLE line recognition
1 = Wake up by address mark (last data bit set)
0 = Short idle line mode is enabled.
1 = Long idle line mode is detected.
