Power-Up Write Inhibit
If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands
on the rising edge of WE#. The internal state machine is automatically reset to the read mode
on power-up.
Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software in-
terrogation handshake, which allows specific vendor-specified software algorithms to be used
for entire families of devices. Software support can then be device-independent, JEDEC ID-
independent, and forward- and backward-compatible for the specified flash device families.
Flash vendors can standardize their existing interfaces for long-term compatibility.
This device enters the CFI Query mode when the system writes the CFI Query command, 98h,
to address 55h, any time the device is ready to read array data. The system can read CFI
information at the addresses given in Tables 27-30. To terminate reading CFI data, the system
must write the reset command.
The system can also write the CFI query command when the device is in the autoselect mode.
The device enters the CFI query mode, and the system can read CFI data at the addresses
given in Tables 27-30. The system must write the reset command to return the device to
reading array data.
For further information, please refer to the CFI Specification and CFI Publication 100, avail-
able via the World Wide Web at http://www.amd.com/flash/cfi. Alternatively, contact your
sales representative for copies of these documents.
