Ring Event Mask Register 1 (REMR1)
The Ring Event Mask Register 1 (REMR1) is used to mask bits in Register RELR1 If a bit in Register REMR1 is set to One the
corresponding bit in Register RELR1 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
