Changing the source slightly to use a constant that fits in 1 byte,
leads to correct code. (In the function not in the macro, see below
diff, so the code is only different in one place).
A movs instruction is generated for 200, whereas for 400 it is a mov.w
and then a nop at the end of the function for padding.
This may affect other offset calculations but I could not determine why
and which one contributes to the fault.
