My mcu will have periodic checks on the "Host IRQ Pin", if i don't touch any capacitive touch button for a long time. I can't detect the IRQ signal When I put my finger on the capacitive touch button suddenly.But if I put my finger on the capacitive for a period of time, my MCU will detect the IRQ signal with high latency, After the high-latency process,the detect task will returned to normal.I waited quietly for a period of time, the problem arose.

Welcome in the forum!
As I understand your MCU is polling too slow. Poll faster or use an interrupt could help.
