void I2C_CalculatePEC	(	I2C_TypeDef *	I2Cx,
		FunctionalState	NewState
	)

Enables or disables PEC calculation.

Parameters:

I2Cx,:	where x can be 1 to select the specified I2C peripheral.
NewState,:	indicates the PEC calculation state. This parameter can be: ENABLE or DISABLE.

Return values:

None

uint8_t I2C_GetPEC ( I2C_TypeDef * I2Cx )

Returns PEC value.

Parameters:

I2Cx,:	where x can be 1 to select the specified I2C peripheral.
None

Return values:

The	value of the PEC.
