i.MX RT 1170 Brownout

[AndreasL]

I am investigating brownout detection for the i.MX RT1170, there are more possibilities in reference manual.

What is the best way to realize following behavior?

I want to save the operating data in the internal flash memory if the power fails and restore the data after switching power on.

My idea was to us the internal DCDC convert an us the
"void ANATOP_LP8_BROWNOUT_IRQHandler(void)" to save the data.

Hello AndreasL,

Yes, you may use the brownout interrupt to save the desired data and change power mode. This may help when power is low but won’t help if power is lost abruptly.

I hope that this information helps.
