    It forces the linker to align the region on 32 bit boundaries.

    It is preferable that DCD data items, literal pools and looping branch targets are on the 32-bit / 4-byte boundaries. Similarly a LDRD from memory would need this type of alignment.

    You could pick courser alignment like 8 or 16 byte
