Read CFI Query command
The Read CFI Query command is used to read data from the Common Flash Interface
(CFI). The Read CFI Query Command consists of one Bus Write cycle, to an address within
one of the banks. Once the command is issued subsequent Bus Read operations in the
same bank read from the Common Flash Interface.
If a Read CFI Query command is issued in a bank that is executing a Program or Erase
operation the bank will go into Read CFI Query mode, subsequent Bus Read cycles will
output the CFI data and the Program/Erase controller will continue to Program or Erase in
the background. This mode supports asynchronous or single synchronous reads only, it
does not support synchronous burst reads.
The status of the other banks is not affected by the command (see
Read CFI Query command, a Read Array command should be issued to the addressed
bank to return the bank to Read Array mode. Dual operations between the
Parameter Bank and the CFI memory space are not allowed (see
limitations).
See
for details on the information contained in the Common Flash Interface memory area.
Clear Status Register command
The Clear Status Register command can be used to reset (set to ‘0’) error bits SR1, SR3,
SR4 and SR5 in the Status Register. One bus write cycle is required to issue the Clear
Status Register command. After the Clear Status Register command the bank returns to
read mode.
The error bits in the Status Register do not automatically return to ‘0’ when a new command
is issued. The error bits in the Status Register should be cleared before attempting a new
Program or Erase command.
