Hi, all


As I understand that all the GPIO pins of iMX28 can be set as interrupt input pins triggered with either level or edge. But I can not find the info about interrupt input signal which can trigger iMX28 through its' gpio pins. For example, what is the minimum pulse width in falling edge trigger mode. Please let me know if anybody have related information about imx28 gpio interrupt. Thanks in advance.
