…
Bit 13: GP8 manual trigger.
Primary counter maximum value.
Secondary counter maximum value.
Mask VD/HD during counter operation.
Number of fields to delay before the next count
(exposure) starts.
ShotTimer with RapidShot, skip delay before first count
(exposure).
Number of fields to delay before the next count starts.
ShotTimer with RapidShot, skip delay before first count.
Selects protocol for each general-purpose signal.
