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 will be inserted instead of data from the
ADCs. When using this mode, disable Row Noise
Correction (Reg0x70 bit 0 and bit 8). If Row Noise
Correction is enabled, the row-wise correction
algorithm will process the test data values and the
result will not be accurate.
Use only when bit 10 is set.
When set, the Two-Wire Test Data (bits 9:0) will be
used in place of the data from ADC/memory on odd
columns, while complement of the same data will be
used on even columns.
