Default = 1.25
System Gain ( G ) is applied to all channels. By default, G = 1.25, but can be finely adjusted to compensate for
voltage reference error. It is a two's complement value in the range of -2.0 ≤ value < 2.0, with the binary point
to the right of the second MSB. Values should be kept within 5% of 1.25.
Default = 0
System Time ( Time ) is measured in output word rate (OWR) samples. This is an unsigned integer in the range
of 0 to 16,777,215 samples. At OWR = 4.0 kHz, OWR will overflow every 1 hour, 9 minutes, and 54 seconds.
Time can be used by the application to manage real-time events.
