7.6.2.14 Shunt-Voltage Sum Register (address = 0Dh) [reset = 00h]
This register contains the sum of the single conversion shunt voltages of the selected channels based on the
summation control bits 12, 13, and 14 in the Mask/Enable register.
This register is updated with the most recent sum following each complete cycle of all selected channels. The
Shunt-Voltage Sum register LSB value is 40µV.

7.6.2.15 Shunt-Voltage Sum-Limit Register (address = 0Eh) [reset = 7FFEh]
This register contains the value that is compared to the Shunt-Voltage Sum register value following each
completed cycle of all selected channels to detect for system overcurrent events. The Shunt-Voltage Sum-Limit
register LSB value is 40µV.
