INC is a short (2 bytes) and fast (12 clocks) way to manipulate the DPS bit in the AUXR1 SFR. However,
note that the INC instruction does not directly force the DPS bit to a particular state, but simply toggles it.
In simple routines, such as the block move example, only the fact that DPS is toggled in the proper sequence
matters, not its actual value. In other words, the block move routine works the same whether DPS is '0' or '1'
on entry. Observe that without the last instruction (INC AUXR1), the routine will exit with DPS in the
opposite state.
