B0S1_n each channel’s transmitted pulse can be made independently
user programmable by selecting “Arbitrary Pulse” mode in
Table 5. The arbitrary pulse is divided into eight time seg-
ments whose combined duration is equal to one period of
MCLK.
This 7 bit number represents the amplitude of the nth chan-
nel's arbitrary pulse during the first time segment. B6S1_n-
B0S1_n is in signed magnitude format with B6S1_n as the
sign bit and B0S1_n as the least significant bit (LSB).
