HW kill-switch for BLE on QN908x

Hello,

On QN908x is there a hardware register kill-switch bit for the entire BLE periphery?

Sometimes it just refuses to shutdown to PD0. Happens like once in 1800-32400 shutdowns.


We need to use CPU register retention, SDK: 2.2.0, bare metal.

I found this mentioning of silicon bug, please see attachment, although it is not mentioned in errata!!

Hello,

The documentation is being updated as well as the workaround for the issue. This is being handled in the internal case as well
