SYNL—Sync Length (Transparent Mode Only)
This field determines the operation of the SCCx receiver that is configured for totally
transparent operation.
RTSM—RTS Mode
This bit indicates the mode of the request-to-send modem signal. It can be changed on-the-
fly.

00 = The sync pattern in the DSR (described in Section 16.9.4 Data Synchronization
01 = 4-bit sync. The receiver synchronizes on a 4-bit sync pattern stored in the DSR.
10 = 8-bit sync. The receiver synchronizes on an 8-bit sync pattern stored in the DSR.
11 = 16-bit sync. The receiver synchronizes on a 16-bit sync pattern stored in the DSR.
0 = Send idles between frames as defined by the protocol and the TEND bit in the
1 = Send flags/syncs between frames according to the protocol. RTSx is always
0 = Normal operation.
1 = If the CDS bit is set to 1, then the CDx signal must be asserted on the second bit

This character and additional syncs can be programmed to be stripped using the
Sync character in the parameter RAM. The transmitter transmits the entire
contents of the DSR prior to each frame.
