Does Softdevice use RTC?

[Justin]

Hi,

I am using nRF52832 along with Softdevice 6.0.0, SDK 15.0.0, Chip Revision 2 (QFAA-EX0).

I need clarification if softdevice uses RTC and if so is the Errata 20 applicable to it?

I understand from errata that read from RTC will not contain the correct value when RTC is coming out of idle state.

If softdevice is reading the RTC, how can the workaround provided in Errata document can be applied in softdevice code?

Regards,

Justin

Hi,

The softdevice is using RTC0, and this errata is fully handled by the softdevice and not something the application need to consider for RTC0. You can safely presume that all peripherals used by the softdevice will apply or use workarounds described in the erratas, unless the errata mention otherwise.

The actual peripherals used by the softdevice can be found in the softdevice documentation, for instance see for S112 softdevice:

Here is an example of a workaround for the RADIO that require a new softdevice to be used:
