21.2.3.7 SYSCFG_I2CFastModePlusConfig
Function Name
void SYSCFG_I2CFastModePlusConfig ( uint32_t
SYSCFG_I2CFastModePlus, FunctionalState NewState)
Function Description
Configures the I2C fast mode plus driving capability.
Parameters
 SYSCFG_I2CFastModePlus : selects the pin. This
parameter can be one of the following values:
 SYSCFG_I2CFastModePlus_PB6 : Configure fast
mode plus driving capability for PB6
 SYSCFG_I2CFastModePlus_PB7 : Configure fast
mode plus driving capability for PB7
 SYSCFG_I2CFastModePlus_PB8 : Configure fast
mode plus driving capability for PB8
 SYSCFG_I2CFastModePlus_PB9 : Configure fast
mode plus driving capability for PB9
 SYSCFG_I2CFastModePlus_I2C1 : Configure fast
mode plus driving capability for I2C1 pins
 SYSCFG_I2CFastModePlus_I2C2 : Configure fast
mode plus driving capability for I2C2 pins
 NewState : new state of the DMA channel remapping. This
parameter can be:
 ENABLE : Enable fast mode plus driving capability for
selected I2C pin
 DISABLE : Disable fast mode plus driving capability for
selected I2C pin
Return values
 None.
Notes
 For I2C1, fast mode plus driving capability can be enabled on
all selected I2C1 pins using
SYSCFG_I2CFastModePlus_I2C1 parameter or
independently on each one of the following pins PB6, PB7,
PB8 and PB9.
 For remaing I2C1 pins (PA14, PA15...) fast mode plus driving
capability can be enabled only by using
