External Interface Read Timing - Normal Mode
Figure 13
performing a Read operation in NORMAL mode. In
the Wait state generator has been configured to provide 2 Wait states during Read
operations. For proper data hold time determination, you must know that the input data is
captured on chip during the rising edge of the system clock prior to the RD signal de-
assertion. The Read signal (RD) timing is shown for both NORMAL and ISA modes.
