Remove LF clock from nRF52832

[JIYEON]

Hello,

Currently In customized PCB board, nRF52832 is connected to both HFCLK(32MHz) and LFCLK(32MHz).

It takes up too much space. So HW engineer asked me to consider remove LFCLK.

Is it possible to remove LFCLK?

Our project is based on ESB example. And It use SPI communication, sleep/wake-up function.

Hi. I have custom board without LFCLK.

The following modifications were made in sdk_config.h

#define NRF_SDH_CLOCK_LF_RC_CTIV 16
#define NRF_SDH_CLOCK_LF_SRC 0
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2
#define NRF_SDH_CLOCK_LF_ACCURACY 1

It's working with SPI and BLE.

But I don't know if sleep/wake-up functionality will be working.
