OPT3002: End-of-convertion Mode and Low Limit register conflict

Part Number:OPT3002

Hi everyone. I'm using OPT3002 and I have a doubt about the register configuration. In particular I want to use the End-of-convertion Mode and the Low Limit register. Is that possibile? I understand that if I want to use the End-of-convertion Mode I have to put LE[3:2] to 11b. So what about the Low limit register? Which is its value?

Thank you.
