# 1.1.4.20 DRV_METROLOGY_GetPerCycleAccData Function

## C

    DRV_METROLOGY_REGS_PERCYCLE_ACC * DRV_METROLOGY_GetPerCycleAccData (void);

## Summary

Get the pointer to the per-cycle accumulator registers of the metrology library application running on the second processor.

## Description

Per-cycle Accumulator registers are acting as 64-bit metrology output accumulator registers. All values are integrated at an equivalent sampling rate of 4.000 kHz. The Metrology library shall generate the following primary output measurement quantities for each Full Line Cycle, per-phase quantities with each phase designated by the subscript “_x” (where x = [A, B, C or D] for voltage channels and x = [A, B, C or N] for current channels) For a detailed description of the control registers, refer to the `drv_metrology_regs.h` header file.

## Parameters

None.

## Returns

Pointer to the 64-bit metrology per-cycle accumulator registers.

## Example

        /* Get Pointers to metrology data regions */
        app_metrologyData.pMetControl = DRV_METROLOGY_GetControlData();
        app_metrologyData.pMetStatus = DRV_METROLOGY_GetStatusData();
        app_metrologyData.pMetAccData = DRV_METROLOGY_GetAccData();
        app_metrologyData.pMetPCAccData = DRV_METROLOGY_GetPerCycleAccData();
        app_metrologyData.pMetHarData = DRV_METROLOGY_GetHarData();

## Remarks

None.
