| FT22 | falling trigger event configuration bit of configurable event input 22 Note: The configurable event inputs are edge triggered. No glitch must be generated on these inputs. If a falling edge on the configurable event input occurs while writing to the register, the associated pending bit is not set. Note: Rising and falling edge triggers can be set for the same configurable event input. In this case, both edges generate a trigger. 0 (B_0x0): falling trigger disabled (for event and interrupt) for input line 1 (B_0x1): falling trigger enabled (for event and interrupt) for input line |
