Writing this file with any value triggers an event 7 driven driver, associated with this trigger, to capture data 8 into an in kernel buffer. This approach can be valuable during 9 automated testing or in situations, where other trigger methods 10 are not applicable. For example no RTC or spare GPIOs. 11 X is the IIO index of the trigger. 12
