    101101== System Temperature and Voltage Monitor ==
    102 The GSC implements system voltage and temperature monitoring (similar to industry standard AD7418) at i2c slave address 0x29. For each analog to digital converter (ADC) input, the value can be read at a register offset. A single temperature sensor provides the board temperature in a 16-bit value (MSB first, LSB second) at register offset 0x00 in degrees Celcius. The voltage based ADC inputs provides a voltage (millivolt) as a 24-bit value (MSB first, LSB last). The ADC measurements are performed once per second (1Hz).
