IRQ Clearing (Register 0x0A05 to Register 0x0A0E)

The IRQ clearing registers are identical in format to the IRQ monitor registers (Register 0x0D08 to Register 0x0D10). When set to Logic 1,

an IRQ clearing bit resets the corresponding IRQ monitor bit, thereby cancelling the interrupt request for the indicated event. The IRQ

clearing registers are autoclearing.
