5.1.2 Reference Voltage Adjust Registers
The analog register block allows programming the input
voltage range of the analog to digital converter to match
the saturation voltage of the pixel array. The voltage ref-
erence generator can be programmed via two registers;
nrv (0 to 1.25V)
in 5mV steps. A 00

Description
Description
a reference output voltage of 2.5V. A 00
nrv register represents output voltage of 0V. The de-
fault settings for the two registers produce a 1.9V refer-
ence on prv and 0.6V on nrv outputs. When adjusting
these values, the user should keep the voltage range
centered around 1.25V.
