(a) When switching the mode using the dedicated instruction (G(P).OFFGAN)
The following program switches to the offset/gain setting mode with the dedicated
instruction (G(P).OFFGAN), changes the channel where offset/gain setting will be
made, writes the offset/gain values to the Q66AD-DG, and then switches to the
normal mode.
