Arbitrary Transmit Pulse Shape, Segment 7

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 seventh time segment.

B6S7_n-B0S7_n is in signed magnitude format with B6S7_n

as the sign bit and B0S7_n as the least significant bit (LSB).
