Value
Bit 7 and Bit 6 of the Interrupt Request register (see
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 1 to any of these bits generates an interrupt if the
appropriate bits in the Interrupt Mask register are enabled. Writing 0 to these bits clears
the interrupts.
