Configuring input pull-up or pull-down

Hi,

I am using the STM32F103ZG device and looking through the reference manual (RM0008) I cannot find how, when a pin is configured as "Input Pull-up/pull-down", to select the pull-up or pull-down option.

Having done some experimentation it appears that this can be done by setting the ports output level high (for pull-up) and low (for pull-down) operation after the pin has been configured as an input.

Is this the indended way to do this? If not, an explanation on how it should be done would be appreciated.

Regards
Farmer
