Note:
The CRA listed in the advanced data sheet described the 2048x1536 field of view (2.908mm image
height). This information was sufficient for configuring the sensor to read both the 4:3
(2048x1536) and 16:9 (2304x1296) aspect ratios. The CRA information listed in the data sheet has
now been updated to represent the entire pixel array (2304x1536).
Read the Sensor CRA
Follow the steps below to obtain the CRA value of the Image Sensor:
1. Set the register bit field R0x301A[5] = 1.
2. Read the register bit fields R0x31FA[11:9].
3. Determine the CRA value according to Table 45.
