Hi my company is trying to find a way to read the frequency of that 32 Mhz external oscilator on nRF52840.
As we cannot directly probe the oscilator due to the capacitor of the probe tampering the readings, we have thought about enabling the QSPI to have that 32Mhz clock directed to one of those GPIO pins as a SPI clk.
Could you guys give some guidance as how to enable 32Mhz oscillator to show up as a spi clock on one GPIO pin?
Thanks.
