the IFP modules. These modules are identified in
Table 7 on page 14 and in Table 8 on page 17. Detailed
register descriptions follow in Table 9 and in Table 10
on page 28. A few registers create effects across a num-
ber of module functions. These include R240 page

0x700E
This register specifies the operating mode of the IFP .
Enables manual white balance. User can set the base matrix and color channel gains. This bit must be
asserted and de-asserted with a frame in between to force new color correction settings to take effect.
Enables auto exposure.
Enables on-the-fly defect correction.
Reserved—obsolete. The user should write “0” to this bit.
Not used.
Enables lens shading correction.
1: Enables lens shading correction.
Reserved.
Enables flicker detection.
1: Enables automatic flicker detection.
Reserved for future expansion.
Reserved.
Bypasses color correction matrix.
1: Outputs “raw” color bypassing color correction.
0: Normal color processing.
Auto exposure back light compensation control.
“00”—Auto exposure sampling window is specified by R38:2 and R39:2 (“large window”).
“01”
“1X”
small window, with the small window weighted four times more heavily.
