| Analogous to PWM a pulsed current is generated at the pin. It is always triggered whenever an internal counter flows over. The time duration of the counter is (65556*pulse unit). For IO3 and SPI_INT the same internal counter is used, so that both signals are always in phase. | Analogous to PWM a pulsed current is generated at the pin.
