operation is not performed. This command has the same protocol as the Write Sector(s) command. The sectors
should be pre-erased with the Erase Sector(s) command before this command is issued. If the sector is not pre-
erased a normal write sector operation will occur. Table 106 defines the Write Sector(s) without Erase command
