This command issues a WRITE-NE to write a byte value to one byte within the static memory 
model area of blocks 0x0-0xE. It does not erase the value of the targeted byte before writing 
the new data. Execution time of this command for NFC Forum tags type 1 is approximately half 
that of the normal write command (WRITE-E). Using this command, EEPROM bits can only be 
set, not reset.
