The interrupt-driven keypad scanning method and apparatus accurately interprets keypresses in single-keypress applications. Initially, interrupts associated with each column line of a keypad matrix are set to trigger when a key is pressed. Once an interrupt triggers, a microcontroller polls the row lines to determine which key, if any, was validly pressed. If exactly one keypress is detected, the keypress is valid. Next, the interrupt for the valid key's column line is enabled while the other column line interrupts are disabled. When a next interrupt is received, the keypad returns to the row-scan state for determination of which keys are depressed. If no keys are depressed, which occurs when the validly-pressed key has been released, the keypad returns to the keypress-detect state.
