OPT9221: How can I generate a DC (non-modulated) illumination pulse between modulated exposures

Part Number: OPT9221
Other Parts Discussed in Thread: OPT8241

Good day,

Our product combines the opt8241 and several CMOS global shutter sensors.  The illumination is common to both.  How can I control the modulation differential pair in order to switch the illuminators on without modulation between opt8241 exposures?  We are using lumped dead time, so ideally this could occur during the dead time.  So far I have found the modulation hold functionality, but this seems only to work during the TOF exposure.

Thanks,

Dave
