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 second time segment. B6S2 -B0S2 is in signed mag-
nitude format with B6S2 as the sign bit and B0S2 as the least
significant bit (LSB).
