B6S5_n - Arbitrary Transmit Pulse Shape, Segment 5
R/W
0
B0S5_n _{The shape of 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 segments 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 fifth time segment. B6S5_n-
B0S5_n is in signed magnitude format with B6S5_n as the
sign bit and B0S5_n as the least significant bit (LSB).

B0S6_n _{The shape of 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 segments whose combined duration is equal to one

B0S6_n is in signed magnitude format with B6S6_n as the
sign bit and B0S6_n as the least significant bit (LSB).
