Hi all, I connect the pin PA2 (pin42 of Cypress CY7C68013 56-pin SSOP) to a push button. When I push the button, there will be a 3.3 voltage applied to pin PA2. I can enable pin PA2 for input and read its state. However, I thinks it is not good solution because user normally presses and releases the push button in very short time. Therefore, when the firmware reads the state of IOA2, user already released the button -> the push button event will be not recorded. Is there any method to raise interrupt when PA2 pin is set?
