UARTE baudrates on nRF52

[NewtoM]

Hello,

I've just read the thread explaining the UART baudrate register settings. I then looked at the nrf52_bitfields.h file and found that the baudrate register values are different for UART and UARTE.

Why the difference and what is the equation to calculate UARTE register values for a given baud rate?

Thanks, NewtoM

The baudrate is actually calculated the same way for both UART and UARTE. The values calculated for UART (legacy mode) was done some time ago, but when they were calculated for UARTE, more accurate values where found.

The baud rate generator is too complex to be described by a simple equation, but the equation in the thread explaining the UART baudrate register will be a good approximation.

Thanks, Sigurd! Any ideas about the issue I mentioned in my comment above?
