Write Sector(s) without Erase (38h)
This command is similar to the Write Sector(s) command with the exception that an implied
erase before write 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 83 defines the Write Sector(s) without Erase command
Byte sequence.
