Paul Mundt lethal at linux-sh dot org writes:
We can't use trapa #0xff on sh2, the only permissible trapa ranges are
32 to 63. On SH-2, we use trapa32 to issue a break in the same way that
trapa #0xff is used on SH-3/4. This behavior is implementation specific,
but is what is used in sh-ipl+g, linux, eCos, uITRON, etc. so we follow
suit here.
