Shadow Register Transfer Control
Figure 18-42 and Figure 18-43 give an overview on the shadow register structure and
the shadow transfer signals, as well as on the read/write accessibility of the various
registers. Providing a shadow register for values describing one PWM period facilitates
a concurrent update by software for all relevant parameters. The next PWM period can
run with a new set of parameters.
