Does NVIC_SystemReset have any disadvantages on the device?

[Vala]

Hi,

I am using nRF52832 as the core of my device that works with battery. I have to keep the SoC powered on all the time. When the off push-button is pressed I restart the MCU using NVIC_SystemReset command and then at the beginning of the code I put the device (and all other components of the system) in power down mode. Therefore the NVIC_SystemReset command might be executed several times a day. My question is that deos NVIC_SystemReset do any harm to the MCU?

That depends entirely on your code, which we don't see here. Unless you write to flash in your code you should be good.

Hi Turbo J, Thanks for your answer. I use a delay before executing that command and disable all the peripherals. So I assume there is nothing going on when I restart the MCU. So it would be OK.

It should be safe to execute this function as it is doing nothing much than just writing to SCB registers in ARM. So you can do that as many times you need. If you are not writing anything to flash then you do not need to worry about any wear off.
