Command interface
All Bus Write operations to the memory are interpreted by the command interface.
Commands consist of one or more sequential Bus Write operations. The commands are
summarized in
descriptions below.
Read Memory Array command
The Read Memory Array command returns the memory to Read mode. One Bus Write cycle
is required to issue the Read Memory Array command and return the memory to Read
mode. Subsequent Read operations will output the addressed memory array data. Once the
command is issued the memory remains in Read mode until another command is issued.
From Read mode Bus Read commands will access the memory array.
Read Electronic Signature command
The Read Electronic Signature command is used to read the Manufacturer code, the Device
code, the Block Protection Configuration Register and the Burst Configuration Register. One
Bus Write cycle is required to issue the Read Electronic Signature command. Once the
command is issued, subsequent Bus Read operations, depending on the address specified,
read the Manufacturer code, the Device code, the Block Protection Configuration or the
Burst Configuration Register until another command is issued; see
electronic
Read Query command
The Read Query command is used to read data from the common Flash interface (CFI)
memory area. One Bus Write cycle is required to issue the Read Query command. Once
the command is issued subsequent Bus Read operations, depending on the address
specified, read from the common Flash interface memory area.
