No errors are returned by this vector call.

  • All registers not shown above are not used on entry and are preserved on exit.
  • This must not be called in supervisor mode unless A0 is zero.
  • If D0.L is positive no action is taken.

The example below shows the use of this trap call to print the error code in D0.L to the channel whose ID is in A0.L.
