access causes a match. Thus if configured for a byte access of a particular address, a word access covering
the same address does not lead to match.
Assuming the access direction is not qualified (RWE=0), for simplicity, the size access considerations are
shown in
Access direction can also be used to qualify a match for Comparator B in the same way as described for
Comparator C in
6.4.2.1.3
Comparator A offers address, direction (R/W), access size (word/byte) and data bus comparison.

A word access of ADDR[n-1] also accesses ADDR[n] but does not generate a match.
The comparator address register must contain the exact address from the code.
Word and byte accesses of ADDR[n]
Word accesses of ADDR[n] only
Byte accesses of ADDR[n] only
