reset to the read mode on power-up.
The Common Flash Interface (CFI) specification outlines device and host system
software interrogation handshake, which allows specific vendor-specified soft-
ware algorithms to be used for entire families of devices. Software support can
then be device-independent, JEDEC ID-independent, and forward- and back-
ward-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 in word mode (or address AAh in byte mode), any
time the device is ready to read array data. The system can read CFI information
at the addresses given in Tables 7–10. To terminate reading CFI data, the system
must write the reset command.The CFI Query mode is not accessible when the
device is executing an Embedded Program or embedded Erase algorithm.
The system can also write the CFI query command when the device is in the au-
toselect mode. The device enters the CFI query mode, and the system can read
CFI data at the addresses given in Tables 7–10. The system must write the reset
command to reading array data.
For further information, please refer to the CFI Specification and CFI Publication
100. Contact your local sales office for copies of these documents.
