Register Description

Table 6: Register Descriptions

REGISTER BIT

DESCRIPTION

Chip ID

0x00

Row Start

0x01

15:0 This register is read-only and gives the chip identification number: 0x1611.

10:0 First row to be read out—default = 0x0014 (20), register value must be an even number.

Column Start

0x02

11:0

First column to be read out—default = 0x0020 (32), register value must be an even number.

Note: If column bin is enabled, the value must be a multiple of Reg0x23 [5:4] + 1.

Row Size

0x03

10:0 Window height (number of rows - 1)—default = 0x5FF (1535), register value must be an odd

number. Minimum value for 0x03 = 0x0001.

Column Size

0x04

10:0

Horizontal Blank

0x05

10:0

Window width (number of columns - 1)—default = 0x7FF (2047), register value must be an odd

number. Minimum value for 0x04 = 0x0001.

Horizontal Blank—default = 0x008E (142 pixels). Minimum value = 0x0015 (21).

Vertical Blank

0x06

10:0 Vertical Blank—default = 0x0019 (25 rows). Minimum value = 0x0003 (3).

Output Control

This register controls various features of the output format for the sensor.

0x07

0 Synchronize changes.

0 = normal operation, update changes to registers that affect image brightness (integration

time, shutter delay, gain, horizontal and vertical blank, window size, row/column skip, or row

mirror) at the next frame boundary.

1 = do not update any changes to these settings until this bit is returned to “0.”

1 Chip Enable.

1 = normal operation.

0 = sensor readout is stopped and analog control signals are put in a state which draws minimal

power.

6 Override pixel data.

0 = normal operation.

1 = output programmed test data (see Reg0x32). First valid columns will output contents of test

data register; second columns will output inverted data. Third columns will output non-

inverted data, fourth inverted, etc.

Shutter Width Upper

0x08

15:0 The most significant bits of the shutter width, which are combined with Shutter Width

(Reg0x09). The total shutter width is therefore: (((Shutter_Width_Upper) x 65536) +

Shutter_Width). This should allow a shutter width from about 50us to about 50s at default row

time.

Shutter Width

0x09

15:0

Number of rows of integration, the exposure time; the time between when the rolling shutter

resets a row and that row is read out, in rows.

Default = 0x0619 (1561). Minimum value = 0x0001 (1).
