The current clock is I0.
S is activated High.
If I0 is currently High, the multiplexer waits for I0 to deassert Low.
Once I0 is Low, the multiplexer output stays Low until I1 transitions High to Low.
When I1 transitions from High to Low, the output switches to I1.
If Setup/Hold are met, no glitches or short pulses can appear on the output.
