T12 Shadow Register Transfer
A special shadow transfer signal (T12_ST) can be generated to facilitate updating the period and compare
values of the compare channels CC60, CC61, and CC62 synchronously to the operation of T12. Providing a
shadow register for values defining 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. The generation of this signal is
requested by software via bit TCTR0.STE12 (set by writing 1 to the write-only bit TCTR4.T12STR, cleared by
writing 1 to the write-only bit TCTR4.T12STD).
