__STATIC_INLINE void LL_I2C_AcknowledgeNextData	(	I2C_TypeDef *	I2Cx,
		uint32_t	TypeAcknowledge
	)

Prepare the generation of a ACKnowledge or Non ACKnowledge condition after the address receive match code or next received byte.

Note:: Usage in Slave or Master mode.

Parameters:

I2Cx	I2C Instance.
TypeAcknowledge	This parameter can be one of the following values: LL_I2C_ACK LL_I2C_NACK
