CFI Query (Note 14)  
Legend:  
X = Don’t care, RA = Address of the memory location to be read, RD = Data read from location RA during read operation,  
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of the WE# or CE#  
pulse. PD = Data to be programmed at location PA. Data is latched on the rising edge of WE# or CE# pulse. SA = Address  
of the sector to be erased or verified. Address bits A21–A16 uniquely select any sector.  
Notes:  
1. See Table 1 on page 11 for descriptions of bus operations.  
2. All values are in hexadecimal.  
3. Except when reading array or autoselect data, all bus cycles are write operations.  
4. Address bits are don’t care for unlock and command cycles, except when PA or SA is required.  
5. No unlock or command cycles required when device is in read mode.  
6. The Reset command is required to return to the read mode when the device is in the autoselect mode or if DQ5 goes high.  
7. The fourth cycle of the autoselect command sequence is a read cycle.  
8. In the third and fourth cycles of the command sequence, set A21 to 0.  
9. In the third cycle of the command sequence, address bit A21 must be set to 0 if verifying sectors 0–31, or to 1 if verifying  
sectors 32–64. The data in the fourth cycle is 00h for an unprotected sector/sector block and 01h for a protected sector/  
sector block.  
10. The Unlock Bypass command is required prior to the Unlock Bypass Program command.  
11. The Unlock Bypass Reset command is required to return to reading array data when the device is in the Unlock Bypass mode.  
12. The system may read and program functions in non-erasing sectors, or enter the autoselect mode, when in the Erase  
Suspend mode. The Erase Suspend command is valid only during a sector erase operation.  
13. The Erase Resume command is valid only during the Erase Suspend mode.  
14. Command is valid when device is ready to read array data or when device is in autoselect mode.  
15. The data is 85h for factory locked and 05h for not factory locked.
