### INx Commands

INx commands perform an I/O input from the source and place the result into the destination. Width can be byte, word, or doubleword. The syntax is as follows:

    INB( destination, source);
    INW( destination, source);
    INDW( destination, source);

    <destination>  ::= <register>
    <source> ::= <constant>  |  <pio variable>
