Return values
None
Note
By default, The GPIO pins are configured in input floating mode (except JTAG pins).
Parameters
GPIOxwhere x can be (A..I) to select the GPIO peripheral for STM32F40xx/41xx and STM32F427x/437x devices.
Return values
None

void GPIO_PinLockConfig ( GPIO_TypeDef GPIOx,
uint16_t  GPIO_Pin 
)

Locks GPIO Pins configuration registers.

Locks GPIO Pins configuration registers. The locked registers are GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL and GPIOx_AFRH.

Note
The locked registers are GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL and GPIOx_AFRH.
The configuration of the locked GPIO pins can no longer be modified until the next reset.
Parameters
GPIOxwhere x can be (A..K) to select the GPIO peripheral for STM32F405xx/407xx and STM32F415xx/417xx devices x can be (A..I) to select the GPIO peripheral for STM32F42xxx/43xxx devices. x can be (A, B, C, D and H) to select the GPIO peripheral for STM32F401xx devices.
GPIO_Pinspecifies the port bit to be locked. This parameter can be any combination of GPIO_Pin_x where x can be (0..15).
Return values
None
Note
The locked registers are GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL and GPIOx_AFRH.
The configuration of the locked GPIO pins can no longer be modified until the next reset.
Parameters
