FLSDET
FIFO LIMIT STATUS DETECT
The FLSDET is used to determine whether the receiver or trans-
mitter FIFO has reached its limit status. If both FIFOs reach their
limit capacity, this bit will be set to "1".

Arbitrary Pulse Generation
The transmit output pulse is divided into 8 individual segments.
This register is used to program the first segment which corre-
sponds to the overshoot of the pulse amplitude. There are four
segments for the top portion of the pulse and four segments for the
bottom portion of the pulse. Segment number 5 corresponds to
the undershoot of the pulse. The MSB of each segment is the sign
bit.
Bit 6 = 0 = Negative Direction
Bit 6 = 1 = Positive Direction
