| - | The pulse value is 16\ bit in width, but has a **minimum value of 100**, which cannot be fallen below. The value itself is written or read via the GPIO main page or via the [[gpioserver|GPIO server]] or [[commandinterface|command interface]]. The pulse length is internally buffered so that the output signal does not accept any inadmissible states in the event of amendments. | + | The pulse value is 16\ bit in width.
