Cirrus Logic CS2100 part numbers

what is the CS210013 variant of the CS2100 as shown for sale here.
The 210013 part number is not listed in ordering information in CS2100 family datasheets.
Is it a preprogrammed version of the -OTP version?

Hi dfink, thank you for your inquiry. We are looking into this part number variant, and we will update with an answer as soon as we have the details.

Hello dfink, sorry for the delay. We received a response from Cirrus stating this part is “now considered a custom part and will be marked as obsolete in the next price book update.”
