!
When bits 5 to 7 are switched on (or off), a possible bias re-tuning of the video amplifier is
required. Typically this involves adjustment to the camera’s offset level.
Register Address 08H and 09H (Interface DAC)
The registers 08H and 09H are used for the DAC access and for adjustments to the camera in the
various operating modes.
WARNING:
Do not modify these values. An incorrect value can cause a malfunction of the
camera!
Register Address 0AH and 0BH
The registers 0AH and 0BH are NOT used.
Register Address 0CH to 0EH (Mode Register Extended Functions)
The registers 12 – 14 control extended functions for camera adjustment. Register 12 contains
further basic settings for the camera. Register 13 contains the control bits for the extended trigger
modes and functions to deactivate the pre-load of the sensor column addresses. Register 14
contains the flag for switching communication to the ADC module.
