Pro Mini - 1.1v analog reference?

Greetings. Can the Pro mini use the 1.1v internal reference like the Uno? Programming the same? I’m swapping out from an Uno to a mini, the response is not the same, and I am trying to step through debug. Seems like everything should swap over since they are both using the Atmega 328, but I thought I would double check. Please let me know when you have a minute.

Thanks,

Chris
