+| Function Name : _INT_ i_APCI1710_InitTorCounter |
+| (BYTE_ b_BoardHandle, |
+| BYTE_ b_ModulNbr, |
+| BYTE_ b_TorCounter, |
+| BYTE_ b_PCIInputClock, |
+| BYTE_ b_TimingUnit, |
+| ULONG_ ul_TimingInterval, |
+| PULONG_ pul_RealTimingInterval) |
++----------------------------------------------------------------------------+
+| Task : Configure the selected tor counter (b_TorCounter) |
+| 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 tor counter. |
+| |
++----------------------------------------------------------------------------+
+| Input Parameters : |
+|
+ CR_AREF BYTE_ b_ModulNbr : Module number to configure |
+| (0 to 3) |
+| data[0] BYTE_ b_TorCounter : Tor counter selection |
+| (0 or 1). |
+| data[1] BYTE_ b_PCIInputClock : 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. |
+| - APCI1710_GATE_INPUT |
+| Used the gate input for |
+| the base clock. If you |
+| have selected this option,|
+| than it is not possibl to |
+| used the gate input for |
+| enabled the acquisition |
+| data[2] BYTE_ b_TimingUnit : Base timing unit (0 to 4) |
+| 0 : ns |
+| 1 : µs |
+| 2 : ms |
+| 3 : s |
+| 4 : mn |
+| data[3] ULONG_ ul_TimingInterval : Base timing value. |
++----------------------------------------------------------------------------+
+| Output Parameters : PULONG_ pul_RealTimingInterval : Real base timing |
+| data[0] value. |
++----------------------------------------------------------------------------+
+| Return Value : 0: No error |
+| -1: The handle parameter of the board is wrong |
+| -2: Module selection wrong |
+| -3: The module is not a tor counter module |
+| -4: Tor counter selection is wrong |
+| -5: The selected PCI input clock is wrong |
+| -6: Timing unit selection is wrong |
+| -7: Base timing selection is wrong |
+| -8: You can not used the 40MHz clock selection wich |
+| this board |

+| Task : Enable the tor counter (b_TorCounter) from selected |

+| this function. |
+| If you enable the tor counter interrupt, the |
+| tor counter generate a interrupt after the timing cycle|
+| See function "i_APCI1710_SetBoardIntRoutineX" and the |
+| Interrupt mask description chapter from this manual. |
+| The b_CycleMode parameter determine if you will |
+| measured a single or more cycle. |

+| 1 : Tor count each high level|
+| BYTE_ b_ExternGate : Extern gate action selection |
+| 0 : Extern gate signal not |
+| used |
+| 1 : Extern gate signal used. |
+| If you selected the |

+| counter. |
+| If you selected the |
+| continuous mode, the |
+| first high level signal |
+| start the tor counter |
+| |
+| APCI1710_TOR_QUADRUPLE _MODE : |
+| In the quadruple mode, the edge|

+| of 2 signals which are phase |

+| other. |
+| The gate input is used for the |
+| signal B |
+| |
+| APCI1710_TOR_DOUBLE_MODE: |
+| Functions in the same way as |
+| the quadruple mode, except that|
+| only two of the four edges are |
+| analysed per period. |
+| The gate input is used for the |

+| |
+| APCI1710_TOR_SIMPLE_MODE: |
