Grounding of DEC2 pin on nRF52832

[Artem Efremov]

Reference circuitry for nRF52832 with internal LDO setup says that C6 should not be mounted. Does it mean that DEC2 pin (32) should be simply grounded or it can be left open?

Hi,

Earlier version of the reference design had this capacitor mounted, but it was found that it was not needed on the QFN-package reference design. On the WLCSP variant, it is required.

For QFN-package the DEC2 pin should be left unconnected.
