When the WAITSEL bit in the WCR1 register is set to 1, the WAIT signal is sampled at the
falling edge of the clock. If the setup time and hold times with respect to the falling edge of the
clock are not satisfied, the value sampled at the next falling edge is used.
However, the WAIT signal is ignored in the following three cases:
