What restrictions do users need to pay attention when using the GPIO De-bounce function? Datum:2016-07-18
The GPIO De-bounce function is used to filter noise or interference on the pin.
After a voltage signal generates a rising or falling edge, if the time to keep high or low level exceeds the De-bounce time set by the user, a GPIO interrupt occurs.
However, there is a limitation related to this function. When the chip is in Power-down mode, the GPIO De-bounce function is turned off. In other words, when the chip is in Power-down mode, once there is a GPIO signal, the GPIO interrupt occurs if the condition of edge-triggered GPIO interrupt is met.
