nrf52832 FCLK pin

[Hk]

Hi,

My sensor uses SPI communication and need 32.768kHz external clock pin FCLK , I connect 32.768kHz clock to XL1 and XL2 but my problem is which pin can I use it for FCLK ?

What kind of SPI needs a frame clock? The SPI supported on the nRF series is normal SPI, just clock and data.
