What is the difference between HAL UART and HAL USART?

Hi to all!,


Having to write a simple UART device driver for my application (based on a STM32L073 mcu),

I noticed that HAL presents two kind of uart drivers: an HAL UART and an HAL USART.

Digging a little bit into the related HAL code, I would say that HAL USART are more suited to

use USART macrocell as a simple uart; instead HAL UART seems to be more useful when 
a need for LIN/Multimaster mode or IrDA arises. Am I right?


Thanks in advance to everyone would take me a feedback!
