__STATIC_INLINE void LL_I2C_DisableIT_BUF ( I2C_TypeDef * I2Cx )

Disable Buffer interrupts.

Note:: Any of these Buffer events will generate interrupt : Receive buffer not empty (RXNE) Transmit buffer empty (TXE)

Reference Manual to LL API cross reference:: CR2 ITBUFEN LL_I2C_DisableIT_BUF

Parameters:

I2Cx	I2C Instance.

Return values:

None

Definition at line 1152 of file stm32f4xx_ll_i2c.h.

__STATIC_INLINE void LL_I2C_DisableIT_ERR ( I2C_TypeDef * I2Cx )

Disable Error interrupts.

Note:: Macro IS_SMBUS_ALL_INSTANCE(I2Cx) can be used to check whether or not SMBus feature is supported by the I2Cx Instance.; Any of these errors will generate interrupt : Bus Error detection (BERR) Arbitration Loss (ARLO) Acknowledge Failure(AF) Overrun/Underrun (OVR) SMBus Timeout detection (TIMEOUT) SMBus PEC error detection (PECERR) SMBus Alert pin event detection (SMBALERT)

Reference Manual to LL API cross reference:: CR2 ITERREN LL_I2C_DisableIT_ERR
