Why happens the message "component" is outside the master's address range in QSYS?

[Altera_Forum]

In my course I'm designing a flash controller in FPGA and integrating everything with QSYS to load in the board and debug. I connected the controller I made with the clock through an avalon MM breach as it can be seen in the picture 

 https://alteraforum.com/forum/attachment.php?attachmentid=14671&stc=1  , I was getting the error message:   "component" is outside the master's address range The data width of my flash is 24 bits. My teacher has fixed this by editing the breach and inputting a larger data width of 32 bits. And just told me, it has to be larger than the flash, but he did not clarify why and left.  I wish to know the reason for this. thanks in advance.
