Notes: 1. "Halted (retained)" means that internal register values are retained. The internal state
is "operation suspended."
2. "Halted (reset)" means that internal register values and internal states are initialized.
3. In module stop mode, only modules for which a stop setting has been made are halted
(reset or retained).
4. In the power-down mode, the analog section of the servo circuits are not turned off,
therefore Vcc (Servo) current does not go low. When power-down is needed,
externally shut down the analog system power.
