Bits 7 and 6 of the Interrupt Request Register are used to configure the edge detection of
the interrupts for Port 3, bit 1 and Port 3, bit 2. The remaining bits, 5 through 0, indicate
the status of the interrupt. When an interrupt is serviced, the hardware automatically clears
the bit to 0. Writing a 1 to any of these bits generates an interrupt if the appropriate bits in
the Interrupt Mask Register are enabled. Writing a 0 to these bits clears the interrupts
