If the voltgate monitoring circuitry is outside the SoC, what is the thread-hold, and what does it do upon detection?

 

  • Responsibility of Brown out circuitry is that, checks whether voltage is good enough to operate. then hold the reset and release it only when its in operating range.
  • Default voltage value at which Brow out circuit resets RTC is at 1.2V. Software could overwrite this configuration (currently its configured to 1.4V in cold boot).
