Question

TIMPRE HCLK multiplier in F413

In RM0430 rev 7 section 6.2 it is stated that when TIMPRE is set and APB prescaler is 1 or 2 then the timer clock is HCLK.

And when APB prescaler is > 2 then the timer clocks are HCLK * 4.

This is different to the F446 which in RM0390 section 6.2 which states that when APB prescaler is > 4 then timer clocks will be HCLK * 4.

So is the F413 indeed different as stated in the RM or is this a typo in the RM and the F413 is the same as the F446?

    Hello

    Anderson.Robert.002

    ,

    The F413 and

    F446

    products are different regarding this point and thereference manuals are correct.

    In fact, t

    he maximum

    HCLK frequency and the maximum APBs frequencies are not the same.

    With Regards,

    Hi Imen.

    Thanks for the confirmation.

    Also another question will the next update of the Cube Eclipse plug-in implement the TIMPRE setting so that the clock configuration has the correct timer clocks when TIMPRE is set?

    Thanks,

    Bob
