Note:
The device can support a combination of synchronous READ and asynchronous WRITE
operations when the BCR is configured for synchronous operation. The asynchronous
WRITE operation requires that the clock (CLK) be held static LOW or HIGH during the
entire sequence. The ADV# signal can be used to latch the target address, or it can
remain LOW during the entire WRITE operation. CE# must return HIGH when transi-
tioning between mixed-mode operations. Note that the
READ or WRITE cycle. This time is required to ensure adequate refresh. Mixed-mode
operation facilitates a seamless interface to legacy burst mode Flash memory controllers
(see Figure 43 on page 51).
