Mornin,
I have to write a device driver for a chip which allows both port
mapped and memory mapped i/o. Now I know that memory mapped is easier for
the programmer (can use any instruction that can access memory, don't need
to copy out data to look at it etc), but i was wondering was there any
particular reasons why people would choose one over the other.
TIA,
Steve
