AD7418 : OTI function


I have a question from our customer about OTI function of AD7418.
He wants to use A1 input for this OTI function.
But it seems that the OTI only be function for channel 0 from data sheet.

In table-6 "AD7418 Pin Function Descriptions" , indicated as followings.

OTI : This is a logic output. The OTI is set if the result of a conversion on Channel 0 (temperature sensor) is greater than an 8-bit word in the TOTI setpoint register. The signal is reset at the end of a serial read operation.

" OTI only be function for channel 0. "

Is this recognition correct ?

Best regards,
