Shortest timer pulse width in one-shot mode

Dear All,

I am looking to generate short pulses (1us) for an application.  On first appearance, the datasheet looks to be very imprecise as to the shortest pulse that can be generated, i.e.:

"Pulse lengths and waveform periods can be modulated from a few microseconds to several milliseconds using the timer prescaler and the RCC clock controller prescalers."

Aside from "a few microseconds", what is the shortest pulse width that can be generated using the STM32 timers (or, for that matter, GPIOs)?  How is this calculated, and what other factors contribute to this timing (aside from external hardware).
