28.4.3.1.1 Address With Mask

An address received that corresponds to the value written to the Address bits in the Address register (ADDR.ADDR), combined with a mask written to the Address Mask bits in the Address register (ADDR.ADDRMASK), results in an address match. All bits that are masked are not included in the match. Note that writing 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.
