STM32F405: Read 100% duty cycle

I am using STM32F405 in an application and in order to start working with the PWM module I have to check that I read a 100% duty cycle on one channel input.
I've been reading documentation, but it seems that input capture mode only works if there are transitions on the signal. This is not my case; I need to check that I read 100% duty cycle from the beginnning (input signal always to '1').

How can I do this? How should I configure the timer input?
