+| (BYTE_ b_BoardHandle, |
+| BYTE_ b_ModulNbr, |
+| BYTE_ b_ChronoMode, |
+| BYTE_ b_PCIInputClock, |
+| BYTE_ b_TimingUnit, |
+| ULONG_ ul_TimingInterval, |
+| PULONG_ pul_RealTimingInterval)
+
++----------------------------------------------------------------------------+
+| Task : Configure the chronometer operating mode (b_ChronoMode)|
+| from selected module (b_ModulNbr). |
+| The ul_TimingInterval and ul_TimingUnit determine the |
+| timing base for the measurement. |
+| The pul_RealTimingInterval return the real timing |
+| value. You must calling this function be for you call |
+| any other function witch access of the chronometer. |
+| |
+| Witch this functionality from the APCI-1710 you have |
+| the possibility to measure the timing witch two event. |
+| |
+| The mode 0 and 1 is appropriate for period measurement.|
+| The mode 2 and 3 is appropriate for frequent |
+| measurement. |
+| The mode 4 to 7 is appropriate for measuring the timing|
+| between two event. |
++----------------------------------------------------------------------------+
+| Input Parameters : BYTE_ b_BoardHandle : Handle of board APCI-1710 |
+| BYTE_ b_ModulNbr CR_AREF(insn->chanspec) : Module number to configure |
+| (0 to 3) |
+| BYTE_ b_ChronoMode data[0] : Chronometer action mode |
+| (0 to 7). |
+| BYTE_ b_PCIInputClock data[1] : Selection from PCI bus clock|
+| - APCI1710_30MHZ : |
+| The PC have a PCI bus |
+| clock from 30 MHz |
+| - APCI1710_33MHZ : |
+| The PC have a PCI bus |
+| clock from 33 MHz |
+| - APCI1710_40MHZ |
+| The APCI-1710 have a |
+| integrated 40Mhz |
+| quartz. |
+| BYTE_ b_TimingUnit data[2] : Base timing unity (0 to 4) |
+| 0 : ns |
+| 1 : µs |
+| 2 : ms |
+| 3 : s |
+| 4 : mn |
+| ULONG_ ul_TimingInterval : data[3] Base timing value. |
++----------------------------------------------------------------------------+
+| Output Parameters : PULONG_ pul_RealTimingInterval : Real base timing |
+| value.
+| data[0]
++----------------------------------------------------------------------------+
+| Return Value : 0: No error |
+| -1: The handle parameter of the board is wrong |
+| -2: Module selection wrong |
+| -3: The module is not a Chronometer module |
+| -4: Chronometer mode selection is wrong |
+| -5: The selected PCI input clock is wrong |
+| -6: Timing unity selection is wrong |
+| -7: Base timing selection is wrong |
+| -8: You can not used the 40MHz clock selection wich |
