#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:

__LENGTH__ USART frame length.

Return values:

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

#define USART_GETCLOCKSOURCE	(	__HANDLE__,
		__CLOCKSOURCE__
	)

Report the USART clock source.

Parameters:

__HANDLE__	specifies the USART Handle.
__CLOCKSOURCE__	output variable.

Return values:

the	USART clocking source, written in __CLOCKSOURCE__.

#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:

__HANDLE__ specifies the USART Handle.

Return values:

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