Function name
__STATIC_INLINE void LL_USART_ConfigMultiProcessMode
(USART_TypeDef * USARTx)
Function description
Perform basic configuration of USART for enabling use in Multi
processor Mode (several USARTs connected in a network, one of
the USARTs can be the master, its TX output connected to the RX
inputs of the other slaves USARTs).
Parameters
USARTx: USART Instance
Return values
None:
Notes
In MultiProcessor mode, the following bits must be kept
cleared: LINEN bit in the USART_CR2 register,CLKEN bit in
the USART_CR2 register,SCEN bit in the USART_CR3
register,IREN bit in the USART_CR3 register,HDSEL bit in
the USART_CR3 register.
