| | Function Name : _INT_ i_APCI1710_InitTorCounter | |
| | (unsigned char_ b_BoardHandle, | |

| | unsigned char_ b_TorCounter, | |
| | unsigned char_ b_PCIInputClock, | |
| | unsigned char_ 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 unsigned char_ b_ModulNbr : Module number to configure | |
| | (0 to 3) | |
| | data[0] unsigned char_ b_TorCounter : Tor counter selection | |
| | (0 or 1). | |
| | data[1] unsigned char_ 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] unsigned char_ 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 | |
| | -9: You can not used the 40MHz clock selection wich | |
| | this TOR version | |

| | If you enable the tor counter interrupt, the | |
| | tor counter generate a interrupt after the timing cycle| |
| | See function "i_APCI1710_SetBoardIntRoutineX" and the | |

| | | |
| | 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 | |
| | signal B | |
| | | |
| | APCI1710_TOR_SIMPLE_MODE: | |
| | Functions in the same way as | |
| | the quadruple mode, except that| |
| | only one of the four edges is | |
| | analysed per period. | |
