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.

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
