Avoid Timing
Etron Pseudo SRAM has a timing which is not supported at read operation. If your system has multiple
invalid address signal shorter than tRC during over 15µs at read operation shown as in Abnormal Timing, it
requires a normal read timing at leat during 15 µs shown as in Avoidable timing 1 or toggle CE1# to high (
tRC) one time at least shown as in Avoidable Timing 2.
