what is the difference between dmp6 with dmp v6.12

[nices0325]

1. simply dmp 6 worldaccel values represent 0,0,0 but dmp v6.12 shows 0,0,8192 (world accel) on my serial monitor... what would be the difference?

2. In the example code, there says that world accel values are out of gravity but it shows 8192 (Z) on my serial monitor

3. Z value should be 8192 on the flat desk . If I rotate Z axis to other position (e.g. rotate it to Y axis) the value should be zero and Y value should be 8192(gravity value), but Z value goes comes to get increasing... I'm confused that is it right to shows the gravity(g_force)...

thank you for your library as well. thank you
