Counter Increment Mask Register (CIMR)

The Counter Increment Mask Register (CIMR) is used to mask bits from the Counter Increment Latch Register (CILR) If a bit in

Register CIMR is set to One the corresponding bit in Register CILR will be applied to the Interrupt Condition Register which can

then be used to generate an interrupt to the CPU

All bits in this register are set to Zero upon reset
