STM32F437 timer sizes

I see varying information about whether the timers in my STM32F437 are 16 bit or 32. Maybe I missed a table in RM0090 or the data sheet. Could someone please point me to a place where this info might be consolidated?

So far by hit or miss it seems TIM2 is 32 bits and TIM4 is 16?

Thanks,

JH

    Oh yes, and Table 6 in the DS, DocID024244 Rev 10, might provide some insight, too...

    RM0090 deals with this, although not in a single place, you have to read the introduction of all 4 timer chapters.

    But, if you believe me, only TIM2 and TIM5 are 32-bit, the rest is 16 bit.
