This board is addressable in the Industrial Pack I/O space to monitor and
control the status and configuration of up to ten 16-bit counter/timers, two
digital inputs and six digital outputs. The I/O space may be as large as 64,
16-bit words (128 bytes) using address lines A1..A6, but the IP482 uses
only a portion of this space.
The memory space address map for the IP482 is shown in Table 3.2.
Note that the base address for the IP482 in memory space must be added
to the addresses shown to properly access the IP482 registers. Accesses
are generally performed on a 16-bit basis (D0..D15), but 8-bit (D0..D8) (EO)
accesses are possible in most cases.
