∗1 Write is executed when both CE1 and WE are at low and CE2 is at high simultaneously.

∗2 Do not apply the data input voltage of the opposite phase to the output while I/O pin is in output condition.

∗3 tWR1 is tested from either the rising edge of CE1 or the falling edge of CE2, whichever comes earlier, until

the end of the write cycle.
