Explanatory notes for Table 2

"X" signifies "don't care" (that is to say, any value may be input).

The "h" following each code indicates that the number given is in hexadecimal notation.

Addresses A23 to A19 for all commands are "Don't care".

In order for commands other than the read command to be recognized, CS must rise after all the bus cycle input.

*1: "PD" stands for page program data. Any amount of data from 1 to 256 bytes in 1-byte unit is input.

*2: Of the two silicon ID commands, it is for the command with the 9Fh setting that the manufacturer code 62h is first

output. For as long as the clock input is continued, 1Eh of the device code is output continuously, followed by the

repeated output of 62h and 1Eh.

*3: Of the two silicon ID commands, it is for the command with the ABh setting that manufacturer code 62h is first

output when address A0 is "0", and the device code 1Eh is first output when address A0 is "1".

Addresses A7 to A1 are "don't care". For as long as the clock input is continued, 62h and 1Eh are repeatedly

output.
