2.1.4.3 DRV_MCMETROLOGY_Open Function

DRV_MCMETROLOGY_RESULT DRV_MCMETROLOGY_Open (
    DRV_MCMETROLOGY_START_MODE mode, 
    DRV_MCMETROLOGY_CONTROL * pConfiguration
);

Opens the metrology driver according to the mode parameter.

This routine enables the IPC peripheral and, only if a HARD start mode has been selected, handles the reset and clock lines for enabling the metrology library application. On the other hand, SOFT mode does not any effects on metrology library application running in the second processor.

If successful, returns DRV_MCMETROLOGY_SUCCESS. Otherwise, it returns DRV_MCMETROLOGY_ERROR.

This routine must be called after DRV_MCMETROLOGY_Initialize routine is called.
