Initialize LPUART registers according to the specified parameters in LPUART_InitStruct.
- Note:
- As some bits in LPUART configuration registers can only be written when the LPUART is disabled (USART_CR1_UE bit =0), LPUART Peripheral should be in disabled state prior calling this function. Otherwise, ERROR result will be returned.
-
Baud rate value stored in LPUART_InitStruct BaudRate field, should be valid (different from 0).
- Parameters:
-
| LPUARTx | LPUART Instance |
| LPUART_InitStruct | pointer to a LL_LPUART_InitTypeDef structure that contains the configuration information for the specified LPUART peripheral. |
- Return values:
-
| An | ErrorStatus enumeration value:
- SUCCESS: LPUART registers are initialized according to LPUART_InitStruct content
- ERROR: Problem occurred during LPUART Registers initialization
