Hi all,

I want to know the maximum baudrate that I can configure using the MODM7AE70 serial ports.

Thanks

Not as simple a question as one might like.
The baud system can divide by 8 or 16 and have a fractional component.

CPU Clock is 300MHZ.
The Perif_clock is also 300Mhz.

The baud rate setting code is in:
nburn\arch\cortex-m7\cpu\SAME70\source\serial.cpp

So I think the baud can be set as high as 37.5 M baud.

(Perif_clock / 8)
What baudrate do you want?

Better question is I want baudrate XX what is the error at that rate?
