Is it possible to configure an output WITH internal pull-up or pull-down? It would save some parts in SDIO and I2C....

From what I see in stm32f10x_gpio.h, the PU and PD are only availlable on inputs... Is it correct, or is there a way?

#define IS_GPIO_MODE(MODE) (((MODE) == GPIO_Mode_AIN) || ((MODE) == GPIO_Mode_IN_FLOATING) ||

((MODE) == GPIO_Mode_IPD) || ((MODE) == GPIO_Mode_IPU) ||

((MODE) == GPIO_Mode_Out_OD) || ((MODE) == GPIO_Mode_Out_PP) ||

((MODE) == GPIO_Mode_AF_OD) || ((MODE) == GPIO_Mode_AF_PP))
