Notes
1. The MOV.B Rs, @–ER7 instruction should never be used, because it leaves an odd value in the stack pointer (ER7).
For details refer to section 3.3.2, Exception Processing, or to the hardware manual.
2. Execution of MOV.B RnL, @–ERn or MOV.B RnH, @–ERn first decrements ERn by one, then transfers the
designated part (RnL or RnH) of the resulting ERn value.
