7.05.2 ONBOARD POWER DETECTION

An onboard device which is part of the reset circuit constantly monitors the voltage which
powers the board. Normally, the board is powered with 5V. If the supply voltage drops
below 4.65V (a typical threshold), the onboard circuitry will reset the board and the
system. This reset has the same effect on the system as the reset button.
