Interrupt Condition Register (ICR)
The Interrupt Condition Register (ICR) collects unmasked interrupts from the Event Registers Interrupts are categorized into
Ring Events Token and Timer Events Counter Events and Error and Exceptional Status Events If the bit in the Interrupt Mask
Register (IMR) and the corresponding bit in the ICR are set to One the INT0 pin is forced low and thus triggers an interrupt
Note Bits are cleared ONLY by clearing underlying conditions (Mask bit and or Event Bit) in the appropriate Event Register
