I'm using an '877 on a 16bit bus, MSB is PortD, LSB is PortB. I need to =
read or write to the bus, and I would like to know if I can create a =
variable in C which references these two ports as though they were a =
single 16bit unsigned int- so instead of having to do msb and lsb =
operations individually.  PORTB =3D int & 255; PORTD =3D int >> 8;  I =
could use a single variable [eg PORTDB ] in these operations: PORTDB =3D =
int;

obviously the compiler will split it up into 2 8bit operations, and I =
don't even care if the code is smaller or (slightly) larger- but it =
would really make my code easier to get my head around at the moment :)

Thanks
