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 2M8 56 SSOP.

NOTES:
1. PA is the address of the memory location to be programmed.
2. PD is the data to be programmed at byte address.
3. D7 is the output of the complement of the data written to each chip.
4. DOUT is the output of the data written to the device.
5. Figure indicates last two bus cycles of four bus cycle sequence.
