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.
