GPIO speed - does it make any sense when GPIO is input ?

hello forum ,

( STM32F103 ) when using GPIO pin as output we can choose GPIO speed ------------------------------------------------------------------   GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;   GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; ------------------------------------------------------------------- can we choose GPIO speed when it is an input ? what is the effect ? ---------------------------------------------------------------------    GPIO_InitStructure.GPIO_Speed =GPIO_Speed_2MHz;   GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; --------------------------------------------------------------------- thank you #gpio-speed-stm32f103

No. See tables 20 and 21 in RM0008. JW

No, It controls the slew rate of the output stage of the pin.
