With these switches attempts to open the system, or remove socketed components are detected. Attempts to heat a box, to remove potting mate- rial, or to cause RAM R/W errors, are detected by the temperature sensor. If the unit is unplugged from its power source, the switch to battery power is detected. When the battery voltage is too low, a signal is provid- ed for action to be taken Attempts at glitching the reset signal or overvolt- age are detected by the reset voltage timing compare with the VDDO voltage and a delay. If attempts to override the system firmware by applying an overvoltage to VDD are detected, action to protect the internal code can be taken. VDDO for the controller can switch up to 0.2 A..
