13.0 Detailed Register Block Assignments
This section describes in further detail the functional op-
eration of the various MCM20027 programmable regis-
ters. The registers are subdivided into various blocks for
ease of addressability and use (see
In each table where a suffix code is used; h = hex, b =
binary, and d = decimal.

The four Color Gain Registers,
Register, and four Color Tile Row definitions define how
white balance is achieved on the device. Six-bit gain
codes can be selected for four separate colors:
10,
dividual color register is programmable given the gain
function defined in the table. The gain function used de-
pends on what Gain mode (White balance gain mode)
the sensor is set
programs these registers to account for changing light
conditions to assure a white balanced output. The de-
fault value in each register is provides for a unity gain.
In addition, the default CFA pattern color is listed in the
title of each register.
