
GPIO output data port value.

None.
void GPIO_SetBits (
GPIO_Pin)
Sets the selected data port bits.

GPIOx : where x can be (A, B, C, D, E or F) to select the
GPIO peripheral.

GPIO_Pin : specifies the port bits to be written.

None.

This parameter can be GPIO_Pin_x where x can be : (0..15)
for GPIOA, GPIOB, GPIOC, GPIOD or GPIOE; (0..2, 4, 6,
9..10) for GPIOF.
void GPIO_ResetBits (
GPIO_Pin)
Clears the selected data port bits.
