NOTE:
1. RY/BY is an open drain output and should be pulled-up to Vcc with an
external resistor.
2. CS1 and CS3 control the same data bus. Reads cannot be done with CS1
and CS3 both active. CS2 and CS4 control the same data bus. Reads
cannot be done with CS2 and CS4 both active.
3. Address compatible with Intel 1M16 56 SSOP, with the addition of
A20
at pin 8. Also refer to Note 2.
