Peripheral migration

The STM32F0 USART provides best-in-class added features:



A choice of independent clock sources allowing

–

UART functionality and wake-up from low power modes,

–

convenient baud-rate programming independently of the APB clock

reprogramming.



Smartcard emulation capability: T=0 with auto retry and T=1



Swappable Tx/Rx pin configuration



Binary data inversion



Tx/Rx pin active level inversion



Transmit/receive enable acknowledge flags



New Interrupt sources with flags:

–

Address/character match

–

Block length detection and timeout detection



Timeout feature



Modbus communication



Overrun flag disable



DMA disable on reception error



Wake-up from STOP mode



Auto baud rate detection capability



Driver Enable signal (DE) for RS485 mode
