1. The HSE clock source can be either an external crystal/ceramic resonator or an external source (HSE
bypass). Refer to Section HSE clock in the STM8L15x and STM8L16x reference manual (RM0031).
2. The LSE clock source can be either an external crystal/ceramic resonator or a external source (LSE
bypass). Refer to Section LSE clock in the STM8L15x and STM8L16x reference manual (RM0031).
