Hi all...
I have a question regarding the ISA bus: looking at the specs, it seems
that a device can drive the MEMCS16 signal if it want to be serviced
with a 16 bit data bus.
But MEMCS16 is decoded from SA17-SA23 lines address... so it seems that
I cannot have a 16bit device in the low memory (under 0x03FFFF)... is
this right ?
also... can I address an IO device and a memory-mapped device in the
same space (for example at 0xd000) ?
thanks a lot for any comments...
