Table 12-1: Scheme of ¼ sine wave period with 6 bit resolution and 64 ( 32 x 2 ) values
These 64 values represent a quarter sine period in the interval [0 ... π/4[ which is expanded
automatically by the TMC428 to a full sine cosine period (see section 12.1, page 41). The table is sent
to the on-chip RAM of the TMC428 by 32 datagrams:
