Differentiation from AR0141CS

The AR0141IR can be electrically differentiated from the

AR0141CS by reading bits 11:9 in R0x31FA. The

AR0141IR contains a unique value of 4 in these bits. It is

necessary to set R0x301A[5] = 1 prior to reading

R0x31FA[11:9].

Default Readout Order

By convention, the sensor core pixel array is shown with

pixel (0,0) in the top right corner (see Figure 6). This reflects

the actual layout of the array on the die. Also, the first pixel

data read out of the sensor in default condition is that of pixel

(0, 0).

When the sensor is imaging, the active surface of the

sensor faces the scene as shown in Figure 8. When the image

is read out of the sensor, it is read one row at a time, with the

rows and columns sequenced as shown in Figure 8.
