Notes:
1. Note that the UNITADD parameter of the IODEVICE macro must correspond to
one of the addresses defined in the UNITADD parameter of the CNTLUNIT macro.
2. The number of addresses within the ADDRESS definition of the IODEVICE macro
determines the number of addresses that should be configured for the corresponding
host circuit on the SCON (as determined by the Device Low and Device High values).
Note that if no UNITADD parameter is defined within the IODEVICE macro, the
address and range defined by the ADDRESS parameter must fall within the address
range defined for the UNITADD parameter of the CNTLUNIT macro.
3. If the UNITADD parameter has not been defined in the IODEVICE macro, it will
default to the ADDRESS parameter. The Device Low value in the SCON configuration
would then have to take on the same value of the two low order hex digits of the
ADDRESS value.
