+ description:
+ This value depends on the maximum current that can be expected to be
+ measured by ina233 in your circuit, divide Maximum Expected Current
+ by 2^15 and express it in microamps.
+
+ This value will be used to calculate the current/power coefficient for
+ the pmbus and to calibrate the IC.
+
+ For device INA233.
+
+ e.g. Calculate the Maximum Expected Current(A) / 2^15 in micro ampere (uA).
+ 30A / 2^15 = 915 uA
+ If value is close to 1000 uA, can use 1000 uA to minimize rounding errors.
