Setting the Exposure Auto Function Using Direct Register Access
Setting the exposure auto functionality via direct register access is a several step process:
 Set the position and size of Auto Function AOI 1 by setting the value of the Auto AOI 1 Left 
register, the value of the Auto AOI 1 Top register, the value of the Auto AOI 1 Width register, 
and the value of the Auto AOI 1 Height register.
(Note: This step assumes that the Exposure Auto function has been assigned to Auto Function 
AOI 1. If the Exposure Auto function is assigned to Auto Function AOI 2, you would set the Auto 
Function AOI 2 registers.)
 Set the value of the Auto Exposure Lower Limit register and the Auto Exposure Upper Limit 
register.
 Set the value of the Auto Target Value register.
 Enable the gain auto function by selecting the value of the Exposure Auto register to the Once 
or the Continuous mode of operation as desired.
For more information about direct register access, see Section 3.2 on page 21.
