[linuxsh-dev] !!! QUESTION !!! --- What the difference between Memory mode and I/O mode in compact flash?

[NIIBE Y. <gn...@m1...>]

You mean, in the case of connecting it to SuperH.

For i386, the difference is big, because memory access and I/O access
is diffeent thing totally (in hardware and software).

For SuperH, where I/O is mapped to memory address space, there's not
so much.  However, there's one big issue, interrupt. 

It get interrupted only when accessing I/O mode, this is my experience.

Hope this helps.
