Low Frequency I/O Signal Usage

[Eliran Amar]

Hi,
We are using nRF52840 in our design. the pin p0.10 is marked as LOW-FREQUENCY I/O (up to 10Khz) according to your recommended usage.
Our software is design to generate a digital output of 8Mhz at p0.10, it works very well for now.
Can you please explain what is the reason for limiting p0.10 to 10Khz?

Hi,

P0.10 is located near RF antenna pin, using it for high-frequency IO may affect radio performance, see this discussion.
