INT32S DRV_QCounterConfigSys ( PTR_T DeviceHandle， PT_QCounterConfigSys *lpQCounterConfigSys );
On the device indicated by the DeviceHandle, it configures the system parameters of the device.
Some parameters, such as system clock rate (SysClock), timer base period (TimeBase), counter period multiplier (TimeDivider) and cascade mode (CascadeMode), are stored in the PT_QCounterConfigSys, structure pointed by the lpQCounterConfigSys.
| Name | Direction | Range | Description |
| DeviceHandle | input | default | The pointer retrieved from DRV_DeviceOpen which specifies the target device. |
| lpQCounterConfigSys | input / output | default | The pointer to indicate the user-prepared structure PT_QCounterConfigSys that stores system clock rate (INT16U SysClock), timer base period (INT16U TimeBase), counter period multiplier (INT16U TimeDivider) and cascade mode (INT16U CascadeMode). |
| 1. 0 | Successful. |
| 2. InvalidDriverHandle | The Devicehandle is NULL. |
| 3. Other value | Please reference ErrorCodes. |
