• Verify Recipe Match and Acknowledgment

• Once both conditions are met, the recipe match is confirmed.

Error Handling

• After confirming the recipe match, unlatch the Camera_1:O.Data[0].1 bit to complete the recipe switch process.

• Monitor for errors during the process.

• If an error occurs, Camera_1:I.Data[1].1 will turn true.
