NOTE
For misaligned accesses (crossing 64-bit boundary), the access is broken
into two accesses. If both accesses are within the data trace range, two
DTMs will be sent: one with a size encoding indicating the size of the
original access (that is, word), and one with a size encoding for the portion
which crossed the boundary (that is, 3-byte).
NOTE
An STM to the cache’s store buffer within the data trace range will initiate
a DTM message. If the corresponding memory access causes an error, a
checkstop condition will occur. The debug/development tool should use this
indication to invalidate the previous DTM.
