A2D API

A2D API is responsible for configuring and handling the 3 external A2D converters, pins: 37, 43

and 47.

Converter values are between 0 to 255 unit ranges, representing 0-2.3 Volt.

Automatic notifications:

1. Periodical - cyclically with pre-defined period.

2. Threshold - notification upon Voltage (see Figure 5-3):

a. Below the "low limit range".

b. Above the "high limit range".

A2D automatic notification default state is OFF.
