Bits 31:5 Reserved, must be kept at reset value.
Bits 4:0 MASK[4:0]: comparator mask size
Provides the size of the ignore mask applied to the access address for address range
matching by comparator n. A debugger can write 0b11111 to this field and then read the
register back to determine the maximum mask size supported.
