Please someone help me in finding the datasheet for STM32F072RB in order to look into the "Alternate function mapping" of the GPIO pins.

I am using STM32F072RB Nucleo board and in the technical reference manual it is mentioned that "Please refer to the “Alternate function mapping�? table in the device datasheet for the detailed mapping of the alternate function I/O pins.". But I am not able to find any details on alternate function mapping details in the datasheet of STM32F072RB. It would be really helpful if someone could help me in finding the alternate function mapping details.
