Using more than 2ppi groups on S110

[victor passe]

Hi, we have a product that we want to update with new fuctionality, We use latest S110 for NRF51822 and would like to have more than 2 ppi groups useable.

In what scenarios will the softdevice use ppi group 2 and 3? can we use them ourself given that we dont use the features in S110 that uses those groups?

The same goes for the PPI channels 14 and 15

Hi,

The S110 softdevice will use the ppi channels as listed in the S110 softdevice specifications when enabled:
https://infocenter.nordicsemi.com/pdf/S110_SDS_v2.0.pdf

If your application need more ppi groups available you will need to check out the nRF52-series that have additional 2 groups that the application can use.

Best regards,
Kenneth

Yes, i have read the SDS, my question was when the softdevice uses ppi channel 2,3 and PPI 14->15
I have not been able to make the softdevice use those resources in my use case
