Notes
2.
When /CEs is HIGH, /CE and /CE2 are HIGH and CE2 is LOW.
3.
Outputs are disabled within two clock cycles after deselect.
4.
If /GW is set to low level or /BWE is set to low level and one of /BW1 to /BW4 is set to low level,
Q1(A9) is not output.
All bytes WRITE can be initiated by /GW LOW or /GW HIGH and /BWE, /BW1 to /BW4 LOW.
1.
/CEs refers to /CE, CE2 and /CE2. When /CEs is LOW, /CE and /CE2 are LOW and CE2 is HIGH.
