as has the following machine-dependent directives for the H8/300:

.h8300h ¶

Recognize and emit additional instructions for the H8/300H variant, and also make .int emit 32-bit numbers rather than the usual (16-bit) for the H8/300 family.

.h8300s

Recognize and emit additional instructions for the H8S variant, and also make .int emit 32-bit numbers rather than the usual (16-bit) for the H8/300 family.

.h8300hn

Recognize and emit additional instructions for the H8/300H variant in normal mode, and also make .int emit 32-bit numbers rather than the usual (16-bit) for the H8/300 family.

.h8300sn

Recognize and emit additional instructions for the H8S variant in normal mode, and also make .int emit 32-bit numbers rather than the usual (16-bit) for the H8/300 family.

On the H8/300 family (including the H8/300H) ‘.word’ directives generate 16-bit numbers.
