Functional overview

3.47

Universal synchronous/asynchronous receiver transmitter

(USART/UART)

and low-power universal asynchronous receiver transmitter

(LPUART)

The devices embed four universal synchronous receiver transmitters (USART1, USART2,

USART3 and USART6), two universal asynchronous receiver transmitters (UART4, UART5)

and one low-power universal asynchronous receiver transmitter (LPUART1).
