When a wait is specified by software using WCR1 and WCR2 (Wn1, Wn0), and the external wait
mask bit (AnWM) is cleared to 0 in WCR2, the wait input WAIT signal from outside is sampled.
Figure 7.17 shows WAIT signal sampling. A 2-cycle wait is specified as a software wait. The
sampling is performed when the Tw state shifts to the T2 state, so there is no effect even when the
WAIT signal is asserted in the T1 cycle or the first Tw cycle. The WAIT signal is sampled at the
clock fall.
