B6S1 - B0S1 Arbitrary Transmit Pulse Shape, Segment 1
The shape of the transmitted pulse can be made user program-
mable by selecting "Arbitrary Pulse" mode, see
arbitrary pulse is divided into eight time segments whose com-
bined duration is equal to one period of MCLK.
This 7 bit number represents the amplitude of the arbitrary pulse
during the first time segment. B6S1 -B0S1 is in signed magni-
tude format with B6S1 as the sign bit and B0S1 as the least sig-
nificant bit (LSB).
