Check the connection path between the STM32U073's OPAMP1_VOUT and the internal ADC channel (ADC1_IN7 or ADC1_IN8)?

I'm designing a circuit to convert sensor values ​​to ADC using the STM32U073MC (LQFP-80).
Unfortunately, I'm new to the STM32U0 series.

I read the RM0503(Rev 4) Reference manual(page 427) and found that the OPAMP1_VOUT can be connected to ADC1_IN8.

However, I checked the datasheet's(DS14548 - Rev 2 - March 2024) port table(page 32/Table 12. STM32U073x8/B/C pin/ball definition) and it seems to be connected to ADC1_IN7.

1. Which information is correct? (ADC1_IN7 or ADC1_IN8)

2. Also, could you briefly explain how to make the desired connection using CubeMX provided by ST?

  - I wish configure VM_SEL bits as “inverting not externally connected” with CubeMX.
