+    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.
