NAME

CMOVE -- append copper move instruction to user copper list.

SYNOPSIS

    CMOVE( c , a , v )

    CMove( c , a , v )
          a1  d0  d1
    CBump( c )
          a1

    void CMove( struct UCopList *, void *, WORD );

Links: UCopList

FUNCTION

Add instruction to move value v to hardware register a.

INPUTS

c - pointer to UCopList structure a - hardware register v - 16 bit value to be written

RESULTS

This is actually a macro that calls CMove(c,&a,v) and then calls CBump(c) to bump the local pointer to the next instruction. Watch out for macro side affects.
