what does the datasheet mean ? This is the STM32F103C8's datasheet.

In Medium-density devices has 1xPWM timer and 3x16bit timers.

​

​

i know that 16bit timer can be PWM function.

What is the difference between 16bit timer and PWM timer?

​

​

STM32F103C8 timer has timer 1�?timer 2 ...timer 14, this is not 14*timer but 3*timer.

why?

Read the PWM timer definition in the Reference Manual.

Maybe it's the old name for Advanced Timer? (triple PWM for brushless motor control)

[Jack Peacock_2]

If the timer (TIM6, TIM7) has no input or output pins then there's no way to capture PWM input of drive a device with a PWM output. PWM capability is wasted.

ST also likes to include SysTick as a timer, even though it is really a very basic timer, no pins associated with it.

Basic 16-bit timers generally have very specific uses for internal timing, so PWM isn't included.
