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.
