Selects protocol for each general-purpose signal.
Description
6: SLR read (manual).
7: force to idle.
1: manual trigger for GP signals, when Protocol 1 is selected.
Bit [6] : GP1 manual trigger
…
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.
Idle = 0.
No counter association = 1.

Secondary repeat = 6.
Keep on = 7.
Exposure: number of fields to mask SGs.
Exposure plus readout: number of fields to mask SUBCK.
0: SUBCK toggles (Register 0x77) updated on SG line.
1: SUBCK toggles (Register 0x77) updated on UPDATE line (VD-updated)
Skip the SUBCK mask for the first exposure field only. Typically set to 1.
Reserved for test purpose. Must be set to 0.
Line location after VSG line to begin SUBCK pulses.
Must not be set to 1.
