(D) Setting for anti-vibration (VSET)
The gain-up amount and gain-up time can be set when VDET=H.
(VDET can be monitored through the VDETMON pin.)

Note) The gain-up amount set by VSET is valid only when FC2 or FR2 for the focus system or
TC2 or TR2 for the tracking system is written after VSET setting.
(No operation is performed to set servo parameters in the anti-vibration mode only by VSET setting.)
