Hi,

I would like to know if is possible set a timer or other peripheral on the STM32F30x to count up or down
the pulses applied to a pin depending on the logic level applied to a second input. For example if the second input is high the pulse are counted Up instead if the second input is low the pulse are counted Down.

I have carefully read the timer section on the reference manual but have not found how to set the timer to achieve this functionality.
Please let me know. Thank you.
