0050 Date: Januari 2021
0051 KernelVersion: 5.11
0052 Description:
0053 To save battery current, the measurement system is disabled if
0054 the battery is the only source of power. This affects all
0055 voltage, current and temperature measurements.
0056 Write a "1" to this to keep performing telemetry once every few
0057 seconds, even when running on battery (as reported by the online
0058 property, which is "1" when external power is available and "0"
0059 when the system runs on battery).

0066 Date: Januari 2021
0067 KernelVersion: 5.11
0068 Description:
0069 The charger will normally drain the battery while inactive,
0070 typically drawing about 54 microamps. Write a "1" to this
0071 property to arm a special "ship" mode that extends shelf life
0072 by reducing the leakage to about 2.8 microamps. The chip will
0073 remain in this mode (and no longer respond to I2C commands)
0074 until some external power-supply is attached raising the input
0075 voltage above 1V. It will then automatically revert to "0".
0076 Writing a "0" to the property cancels the "ship" mode request.
0077 The ship mode, when armed, activates once the input voltage
0078 drops below 1V.
