Which manual/reference contains detailed register/function specification for (USART) peripherals found in STM32F0 series?

Question

I need to configure one of the USART peripherals in STM32F0 series MCU without using HAL or Low-layer drivers. I plan to fully initialize and drive the USART peripheral registers directly from the application, including assigning the USART to the required GPIO pins of the device.

In manual DM00031936 (RM0091 Reference Manual) Section 27.8.12 Table 110 (partially copied below) tells me the offsets for the registers for a USART device, but not the definition of the individual bits/functions.

Which category of manual or reference document should I use to find this information?

Thank you!
