Register Descriptions (continued)
The 10-bit test data in this register is used in place of
the data from the sensor. The data is inserted at the
beginning of the digital signal processing. Both test
enable (bit 13) and use two-wire serial interface (bit 10)
must be set.
0 = Use Gray Shade Test Pattern as test data.
1 = Use Two-wire Serial Interface Test Data (bits 9:0) as
test data.
0 = None.
1 = Vertical Shades.
2 = Horizontal Shades.
3 = Diagonal Shade.

shaded test pattern to be used as digital test data.
Ineffective when Use Two-wire Serial Interface Test
Data (bit 10) is set.
Enable the use of test data/gray shaded test pattern in
the signal chain. The data is inserted instead of data
from the ADCs.
Set R0x70 bit 5 = 0 when using this mode. If R0x70 bit 5
= 1, the row-wise correction algorithm processes the
test data values and the result is not accurate.
Use only when two-wire serial interface test data (bit
10) is set. When set, the two-wire serial interface test
data (bits 9:0) is used in place of the data from ADC/
memory on odd columns, while complement of the
two-wire serial interface test data is used on even
columns.
Tile Digital Gain = Bits (3:0) x 0.25. See “Gain Settings”
on page 47 for additional information on digital gain.

automatic gain/exposure control algorithm.
