Sabachka,
Instead of this:

        #define CLK    PORTA, 1
        #define DQ      PORTA, 0

I would use:

        #define PORTDS    PORTA
        #define CLK             PORTA, 1
        #define DQ               PORTA, 0
...

        bsf         PORTDS, DQ

This is easy to read and understand but when you assemble the
file it translates to:

bsf PORTA, 0

I hope that this helps.

Andrew
