4.2 Universal Asynchronous Receiver-Transmitter (UART)

STM32G0 and MSPM0 both offer peripherals to perform asynchronous (clockless) communication. These UART peripherals come in two variants, one with standard features and one with advanced features. The naming differences are shown in #GUID-F79CAF60-6475-4AAD-8644-A19C9C32702B/GUID-E49F9AB7-C25E-4325-AF5C-2B0213ADDCAC.
