I/O Addressing
In the 80C88, I/O operations can address up to a maximum
of 64k I/O registers. The I/O address appears in the same
format as the memory address on bus lines A15-A0. The
address lines A19-A16 are zero in I/O operations. The
variable I/O instructions, which use register DX as a pointer,
have full address capability, while the direct I/O instructions
directly address one or two of the 256 I/O byte locations in
page 0 of the I/O address space. I/O ports are addressed in
the same manner as memory locations.
