Command
Renesas Technology Corp.
Execute the clear status register command (50
to clear the status register. Try performing the
operation one more time after confirming that the
command is entered correctly.
Should a block erase error occur, the block in error
cannot be used.
Execute the read lock bit status command (71
to see if the block is locked. After removing lock,
execute write operation in the same way. If the
error still occurs, the page in error cannot be
used.
