How many PPI channels are avilable for app with Sofdevice?

I would like to confirm the number of available and configurable PPI channels for the application code when Softdevice S132 is used. I am using nRF52832.

In the Product Specification V1.0 document, page 165, Table 30 says PPI - Channels 0-19 are configurable.

However, in the Softdevice S132 documentation, S132_SDS_v0.5.pdf, page 44, Table 28

Application: Channels 0-13 Sofdevice: Channels 14-15

And,what about channels 16-19, are they still available for the application while using the Softdevice S132?

Thank you.

  • Hi,

    The S132_SDS_v0.5.pdf is for S132_1.0.0-3.alpha version of the firmware where they use from channel 14-19 because of some hardware issues in our hardware protocols.

    The newer SDS for S132-SD-v2 is not yet released (will be public in few weeks) and for this version of the software the softdevice uses PPI channels 17-19.

    So if you are using S132_1.0.0-3.alpha -> application can use 0-13 and if you are using S132-SD-v2 -> application can use 0-16
