WebThe interrupt output can be configured to activate under two conditions (mutually exclusive): 1. When any input state differs from its corresponding input port register state. This is used to indicate to the system master that an input state has changed. 2. When an input state differs from a pre- configured register value (DEFVAL register). simple bathroom designs greyWeb6 de mai. de 2024 · Open Drain.
