4.1.3

Read CFI Query command

The Read CFI Query Command is used to read data from the Common Flash Interface

(CFI) Memory Area. This command is valid when the device is in the Read Array mode, or

when the device is in Autoselected mode.

One Bus Write cycle is required to issue the Read CFI Query Command. Once the

command is issued subsequent Bus Read operations read from the Common Flash

Interface Memory Area.

The Read/Reset command must be issued to return the device to the previous mode (the

Read Array mode or Autoselected mode). A second Read/Reset command would be

needed if the device is to be put in the Read Array mode from Autoselected mode.

See Appendix B: Common Flash Interface (CFI), Tables 23, 24, 25, 26, 27 and 28 for details

on the information contained in the Common Flash Interface (CFI) memory area.

4.1.4

Chip Erase command

The Chip Erase command can be used to erase the entire chip. Six Bus Write operations

are required to issue the Chip Erase Command and start the Program/Erase Controller.

If any blocks are protected then these are ignored and all the other blocks are erased. If all

of the blocks are protected the Chip Erase operation appears to start but will terminate

within about 100µs, leaving the data unchanged. No error condition is given when protected

blocks are ignored.

During the erase operation the memory will ignore all commands, including the Erase

Suspend command. It is not possible to issue any command to abort the operation. Typical

chip erase times are given in Table 8: Program, Erase times and Program, Erase Endurance

cycles. All Bus Read operations during the Chip Erase operation will output the Status

Register on the Data Inputs/Outputs. See the section on the Status Register for more

details.

After the Chip Erase operation has completed the memory will return to the Read Mode,

unless an error has occurred. When an error occurs the memory will continue to output the

Status Register. A Read/Reset command must be issued to reset the error condition and

return to Read Mode.

The Chip Erase Command sets all of the bits in unprotected blocks of the memory to ’1’. All

previous data is lost.
