These three Exposure Time Limitation Value Registers(24Bits) are used to set the
minimum Frame-Rate. It defines maximum exposure time that can be programmed to
CIS integration time registers. And, It must be programmed as multiple of Anti Flicker
Unit Time Register(24Bits) when AE anti_Flicker mode is enabled.

These Cr, Cb-target Registers are used for controlling Frame Color. AWB logic use
these values for a white balance matching. To make a frame reddish, Increase the Cr
target register value over 80h or decrease the Cb target register value under 80h.

Anti Flicker Unit Time Registers(24Bits) should be used to define the time step of
changing integration time register. AE Anti-Flicker mode is used to remove horizontal
banding noise under fluorescent lamp. When AE anti-flicker mode is enabled, the
integration registers of a CIS are programmed as multiple of this unit time. These
registers are valid only when AE anti-flicker mode is enabled. When AE pixel mode is
enabled, Anti flicker Unit time Registers(24Bits) are used to set exposure time bottom
limitation.
