* battery state of charge, and the other is available for you to use in your

* 1. The red LED on PD7. Part of the (rear-firing) red/green LED.
* 2. The green LED on PE7. Part of the (rear-firing) red/green LED.
* 3. The white (top-firing) LED on PE8
*
* When the I/O is HIGH value, the LED is OFF.
* When the I/O is LOW, the LED is ON.
*
* Following this convention, only the white LED is made available even though they
* all could be user-application controlled if desired.
