3.3 Accumulated Output Quantities
All Metrology 64-bit output accumulator registers are prefixed “Metrology_Acc_Out_”. The start address is 0x20088180. All values are integrated at an equivalent sampling rate of 4000 KHz. The Metrology module generates the following primary output measurement quantities for each measurement interval, per-phase quantities with each phase designated by the subscript “_x” (where x = [A, B, or C] for voltage channels and x = [A, B, C or N] for current channels).
