There is a bug in the simulator for the STM32F103 family involving the timer slave reset.
I downloaded and compiled AN2592 from www.st.com/.../familiesdocs-110.html using uVision 3 V3.55a.
I am using the capture example, in which Timer 3 is a master and Timer 2 is its slave. Timer 3 is reset on the rising edge of its TI1 input.
The timer count registers seem frozen in the simulator. When I use it in real hardware the problem goes away.
