Blue Balance Register (09h at SA 0x34h)

BB[7:0]

The Blue Balance register controls the blue contribution to the B-Y chrominance signal. When

the register value is 00h, the blue contribution is minimized; when the register value is FFh, the

blue contribution is maximized. When the AWB correction is in progress, this register value is

adjusted such that the absolute magnitude of the B-Y signal is minimized.

Red Saturation Register (0Ah at SA 0x34h)

RS[7:0]

The Red Saturation register value controls the amplitude of the R-Y chrominance signal. When

the register value is 00h, the amplitude of the R-Y is minimized; when the register value is FFh,

the amplitude of the R-Y is maximized.

Blue Saturation Register (0Bh at SA 0x34h)

BS[7:0]

The Blue Saturation register value controls the amplitude of the B-Y chrominance signal. When

the register value is 00h, the amplitude of the B-Y is minimized; when the register value is FFh,

the amplitude of the B-Y is maximized.

Gamma Correction Register (0Ch at SA 0x34h)

Writing to the gamma register (0Ch

at SA 0x34h) selects the R, G, and/or B RAM. Continuing data writes without

sending a stop bit after the register write results in writes to the ram locations starting with 00h and continuing to

FFh. Reads from register 0Ch function in a similar way. NOTE: All three gamma rams may be selected for simulta-

neous writes, but read should be done one ram table at a time.

GC0

Logic “1” selects BLUE gamma RAM for subsequent access.

GC1

Logic “1” selects GREEN gamma RAM for subsequent ram access.

GC2

Logic “1” selects RED gamma RAM for subsequent ram access.

GC[0:7]

Provide R/W access to RAM after gamma RAM table has been selected.

Test Control A Register (0Eh at SA 0x34h)
