Detailed Description

EvmuBattery BIOS monitor + low battery detection circuit.

EvmuBattery is an EvmuPeripheral which encompasses two things:

  • A low battery alarm which is asserted on Pin 7.1 when low voltage is detected
  • A monitor within the BIOS which listens for this alarm and tells you to change the battery
Warning
The battery alarm is there to ensure that you don't do something like begin writing to flash with a dying battery, which could result in loss of data and filesystem corruption.
Todo:
  • rig up properties
  • battery lifetime profiler API
