31.6.3.1.1 Address Mask

An address written to the Address bits in the Address register (ADDR.ADDR), and a mask written to the Address Mask bits in the Address register (ADDR.ADDRMASK) will yield an address match. All bits that are masked are not included in the match.
Note: Writing the ADDR.ADDRMASK to “all zeros” will match a single unique address, while writing ADDR.ADDRMASK to “all ones” will result in all addresses being accepted.
