Extension Slot Ac Timing - Hitachi SH7760 Solution Engine2 Overview

9.5 Extension Slot AC Timing

As shown in Figure 9.4, the SH7760 bus signal is output to the extension slot via the bus buffer. For this reason,
the bus signal delays approx. 8nsec for the AC timing of the SH7660 bus. When designing the daughter board,
consider this delay. Figure 9.5 shows the basic bus timing of the SH7760.
For details on SH7760 bus timing, refer to the pertinent SH7760 Hardware Manual.
[Note]
(1) The bus timing delay time must be used only for reference. This is not a guaranteed value.
