Hello, I have looked in the datasheet and there is no "FT" like the stm32 family has. It does show that the UART pins are "HS" (high sink current). Can I assume there is something like a zener diode plus resistor to protect the core from 5 volts? That to me would be a reason why those pins are "HS". I will have a PL2303 USB-to-serial adapter connected to the UART, and it operates at 5 volts. Thank you in advance.
