Notes:
1. Offset errors are removed by enabling the System Monitor automatic gain calibration feature.
2. See "System Monitor Timing" in the Virtex-6 FPGA System Monitor User Guide
3. See "Analog Inputs" in the Virtex-6 FPGA System Monitor User Guide for a detailed description.
4. Any variation in the reference voltage from the nominal V_REFP = 1.25V and V_REFN = 0V will result is a deviation from the ideal transfer
function.This also impacts the accuracy of the internal sensor measurements (i.e., temperature and power supply). However, for external
ratiometric type applications allowing reference to vary by ±4% is permitted.
