Figure 7-2: Hitachi SH-4 Timing
Note
The above timing diagram is not applicable if MD12 = 1 (BUSCLK divided by 2).
Note
The SH-4 Wait State Control Register for the area in which the S1D13506 resides must
be set to a non-zero value. The SH-4 read-to-write idle cycle transition must be set to a
non-zero value (with reference to BUSCLK).
