Advanced_Feature_Unique_ID
(=Feature offset)
For example: The Feature_Id field for the FLIP_INQ CSR would be 0x000168000114
NOTE 2:
You do not have to access the Access Control Register to Read/Write to the value at the offset
pointed to by the value in this register.
NOTE 3:
These are the offsets for the absolute value CSRs for the parameters of GPO 0. The absolute
value CSR offsets for GPO X can be calculated as follows : quadlet offset of Parameter
N
GPO
X
= GPO_PARM
N
_ABS + 3 *
X
.
NOTE 4:
This is the offset for the absolute value CSR for the Extended Shutter Knee Point 0. The absolute
value CSR offsets for Knee Point X can be calculated as follows : quadlet offset of Knee Point
X
= XSHUT_KN 3 *
X
.
NOTE 5:
In all formats the Auto ROI must be within an image region that has Top and Left coordinates of
zero and Height and Width values that correspond to the current Video height and width.
NOTE 6:
Descriptors are added or removed by increasing/decreasing this value. When a descriptor is
created it will have the same values as the current descriptor (Current field) or the camera
settings if it is the first descriptor to be created. When the descriptor number is decreased then
the descriptors with a higher index are removed first.
NOTE 7:
Changing this feature can change the orientation of the Bayer pattern. The Format 7 Color Filter
ID register should be checked each time this feature is changed.
7.1 Extensions to the IIDC Version 1.31 Specification
The following sections describe PixeLINK extensions to the IIDC specification to allow for
extra functionality within the IIDC address space.
7.1.1 Determining which Features can change in a Descriptor
All feature element inquiry registers (Offset 500h to 5FFh) use bit 2 to indicate if the feature
can have different values in different descriptors as shown in Table 12 below.
Table 12 - Feature Element Inquiry CSRs (Section 4.5 in the IIDC 1.31 Spec.)

7.1.1.1 Color Coding
The Color Coding Inquiry Register uses bit 31 to indicate if the color coding can change
between descriptors.
