HW UART - max. baud rate

[elral]

Hello all,
wonderung what the max. baud rate for the both HW serial UART's is I can set with Serial1/2.begin(BAUDRATE);?
I couldn't find any hint on the docu, in the datasheet it's stated that it's depeneding on FUARTCLK, but can't find what this value is.

Thanks and regards

Ralf

From 4.2.1 in the 2040 datasheet:

Supports a maximum baud rate of UARTCLK / 16 in UART mode (7.8 Mbaud at 125MHz)

Whether the core can keep up with interrupts/polling at 1 megabyte/second is an exercise for the reader....

Thanks, that's indeed way more I am thinking about.
