35 / 73 page Revision 8.0 - 28 November 2001 : MCM20027 MOTOROLA 35 MOTOROLA SEMICONDUCTOR TECHNICAL DATA ImageMOS ImageMOS 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 Table 6). In each table where a suffix code is used; h = hex, b = binary, and d = decimal. 13.1 Analog Register Interface Block The address range for this block is 00h to BFh. 13.1.1 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 8, Table 9, Table 10, and Table 11. Gain for each individ- ual color register is programmable given the gain func- tion defined in the table. The gain function used depends on what Gain mode (White balance gain mode) the sensor is set (PGA Gain Mode; Table 25).The user programs these registers to account for changing light conditions to assure a white balanced output. The default 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.
