Manufacturer
Device
I/O0 to I/O7
This mode allows the identification of the manufacturer and product. After the 90h command cycle, one address
cycle follows in which 00h is entered. The next two RE pulses will output the manufacturer and device codes
respectively.
The Status Register may be used to determine if the device is ready, in the write protect mode, or passed
program/erase operations. After the 70h command is entered, the more recent falling edge of either CE or RE
will output the contents of the status register to I/O0 to 7. The status register is continually updated and does
not require either CE or RE to be toggled. By utilizing the CE pin, multiple devices with R/B pins wired together
may be polled to determine their specific status.
