* during the sequence playback. Therefore, you must ensure that the values
* do not change before and during the sequence playback (for example,
* the values cannot be placed in a local variable that is allocated on stack).
* If the sequence is played in a loop and the values should be updated
* before the next iteration, it is safe to modify them when the corresponding
* event signaling the end of sequence occurs (@ref NRF_PWM_EVENT_SEQEND0
* or @ref NRF_PWM_EVENT_SEQEND1, respectively).
*
* @note The @p repeats and @p end_delay values (which are written to the
* SEQ[n].REFRESH and SEQ[n].ENDDELAY registers in the peripheral,
* respectively) are ignored at the end of a complex sequence
* playback, indicated by the LOOPSDONE event.
