◆ IS_USART_WORD_LENGTH

#define IS_USART_WORD_LENGTH ( __LENGTH__ )

Value:

                                          (((__LENGTH__) == USART_WORDLENGTH_7B) || \
                                          ((__LENGTH__) == USART_WORDLENGTH_8B) || \
                                          ((__LENGTH__) == USART_WORDLENGTH_9B))

Ensure that USART frame length is valid.

Parameters

<strong>LENGTH</strong> USART frame length.

Return values

SET	(LENGTH is valid) or RESET (LENGTH is invalid)

◆ USART_MASK_COMPUTATION

#define USART_MASK_COMPUTATION ( __HANDLE__ )

Compute the USART mask to apply to retrieve the received data according to the word length and to the parity bits activation.

Note: If PCE = 1, the parity bit is not included in the data extracted by the reception API(). This masking operation is not carried out in the case of DMA transfers.

Parameters

<strong>HANDLE</strong> specifies the USART Handle.

Return values

None,the mask to apply to USART RDR register is stored in (HANDLE)->Mask field.
