The following SHAPE registers allow custom programming of the transmit signal pulse shapes. Each set of eight
registers determines the shape for its corresponding channel. A channel [n] is configured to use custom shapes by
first programming the eight SHAPEn registers, then setting register bit PPT [addr n2]. For more information on
transmitter functionality, see
