Reset command (FF

+ FF

)
The reset command is used to stop the program command or the erase command in the middle of
operation. After writing command code “40
16
” or “20
16
” twice to the flash command register, write
command code “FF
16
” to the flash command register in the first bus cycle and the same command
code to the flash command register again in the second bus cycle. The program command or erase
command is disabled, with the flash memory placed in read mode.
