5.0 Detailed Register Block Assignments
This section describes in further detail the functional op-
eration of the various MCM20014 programmable regis-
ters. The registers are subdivided into various blocks for
ease of addressability and use (see
Table 1
).
In each table where a suffix code is used; h = hex, b =
binary, and d = decimal.
5.1 Analog Register Interface Block
The address range for this block is 00
h
to 0F
h
.
5.1.1 Analog Color Configuration
The four Color Gain Registers,
Color Tile Configuration
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:
Table 3
,
Table 4
,
Table 5
, and
Table 6
. Gain for each individual
color register is programmable given the gain function
defined in the table. The user programs these registers
to account for changing light conditions to assure a
white balanced output. The default value in each regis-
ter is provides for a unity gain. In addition, the default
CFA pattern color is listed in the title of each register.
