= 0: The receive framing pulse RSFSn is active high.
= 1: The receive framing pulse RSFSn is active low.
In Receive Multiplexed mode, this bit of the four links should be set to the same value.
In Receive Clock Master mode, these bits select what the pulse on RSFSn indicates.

The RSFSn pulses during the first bit of each Basic frame.
The RSFSn pulses during the first bit of each CRC Multi-frame.
The RSFSn pulses during the first bit of each Signaling Multi-frame.
The RSFSn goes high/low during the first bit of each Signaling Multi-frame and goes the opposite during the sec-
ond bit of each CRC Multi-frame.
The RSFSn pulses during the TS0 and TS16.
