Here are a few questions on the following Coldfire MOVEA instruction.
movea.w (%a2)+,%a3 #a3=mem[a2.w]; a2=a2+2
1. Does A3 load 16 or 32 bits? I suspect all 32-bits are loaded from the sign-extended memory location pointed to by A2.
2. Does A2 increment by 2?
3. What does the "%" represent? Is it assembler specific?
Is there overlap/redundency between instructions LEA & MOVEA? Are the following eqivalent?
lea.l (%a2),%a3 #a3=mem[a2]
movea.l (%a2),%a3 #a3=mem[a2]
