external RTC connection to nRF52840

[Balu Varkala]

Hi,

I am using the nRF52840 BLE chip and i need to connect the external RTC(M41T62). I have one doubt M41T62 is having the 32khz o/p pin where should i connect that connection nRF52840.

Please find the attached snapshot below for the same.

What does the nRF52840 datasheet ("Product Specification") tell you about providing a 32kHz clock input ?
