typedef enum

{ GPIO_Mode_AIN = 0x0,

GPIO_Mode_IN_FLOATING = 0x04,

GPIO_Mode_IPD = 0x28,

GPIO_Mode_IPU = 0x48,

GPIO_Mode_Out_OD = 0x14,

GPIO_Mode_Out_PP = 0x10,

GPIO_Mode_AF_OD = 0x1C,

GPIO_Mode_AF_PP = 0x18

}GPIOMode_TypeDef;

How come 0x0, 0x28, 0x48? Which register are they based on?

Thanks, that's right.
