STM32L031K6U6 - ADC Channel 9 Pin Mapping Clarification

[vardhaman_k]

Hello ST Support Team,

I'm working with the STM32L031K6U6 (32-pin UFQFPN package) and need clarification on ADC channel mapping.

Question: Is there an ADC Channel 9 available on the STM32L031K6U6, and if so, which physical pin does it map to?

Context:
- I'm trying to use PB1 as an ADC input
- Documentation suggests ADC Channel 9 should be available

Could you please confirm:
1. Which pins have ADC capability on STM32L031K6U6 32-pin package?
2. Is ADC Channel 9 available on this specific package variant?
3. If ADC Channel 9 exists, which physical pin does it connect to?

Hardware: STM32L031K6U6 (32-pin UFQFPN package)
IDE: STM32CubeIDE
HAL Version: Latest

Thank you for your assistance.
