From ARM DDI 0403.d, p. C1-731:

To find the maximum size of the address comparison mask for comparator n, software must write
0b11111 to the DWT_MASKn.MASK field, and then read the DWT_MASKn register. The value
returned in the MASK field is the maximum mask size.

There also is no function available that queries this maximum mask size.
