Softdevice block register access

[Miroslav]

Hi, I worked with temp sensor example and sofdevice s110 and something stuck on some function. Anyway, I made readout from registers but softdevice blocks register access and code fail. When I delete softdevice I can read temperature easy. Is there any way to prevent softdevice blocking register access?

[Susheel Nuguru]

Which register was your code trying to access? Which API was blocked? which SDK and which SD110 versions did you use? Can you provide some code snippet to show what is blocked and where

[Miroslav]

SD110 v6.0.0, custom PCB project, code stuck on NRF_TEMP->POWER = 1;, if I comment that line it stuck on next NRF_TEMP->INTENSET = 1; and so on... If I delete softdevice code work perfect.

If you read the documentation for the softdevice you'll see the TEMP peripheral is restricted, which means it's blocked from direct access and you can only use it via the softdevice's temperature functions.

The spec gives the full list of open, blocked and restricted peripherals.

But I can acces it without softdevice. So you explination is not correct, it is restricted only when use softdevice.

Which is why I said "if you read the documentation for the softdevice' and 'you can only use it via the softdevices temperature functions'.

Obviously all the peripherals on the chip are available if yours is the only code running, the softdevice uses some resources itself and re-exports them via functions. Again I recommend reading the documentation.
