The interrupt control register (ICR) provides a means of clearing the ISR. When a bit in the ICR is written

with a 1, the corresponding bit in the ISR is cleared, clearing the interrupt output pin IRQ (assuming the

cleared bit in the ISR is the only interrupt source). If the input source to the ISR is a steady-state signal that

remains active, the appropriate ISR bit, and subsequently IRQ, will be reasserted shortly thereafter.

Figure 14-44

complete bit definitions for the ICR can be found in

When an ICR bit is written, it will automatically clear itself one cycle later. That is, it is not necessary to

write a ‘0’ to a bit position which has been written with a ‘1’.
