_Finally, keep in mind that the MCP23008/MCP23017 chip will only store the last interrupt registered in the interrupt register and capture register - Because the interrupt register is only checked every 50 milliseconds by the Tasmota firmware you may experience missed interrupts if your incoming signals fluctuate/change faster than 20 times per second._ _Finally, keep in mind that the MCP23008/MCP23017 chip will only store the last interrupt registered in the interrupt register and capture register - Because the interrupt register is only checked every 50 milliseconds by the Tasmota firmware you may experience missed interrupts if your incoming signals fluctuate/change faster than 20 times per second._
