-|| mode | | description | action ||
-|+--------+-----------------------------+--------------+--------------------+|
-|| |Mode 0 is typically used | | ||
-|| |for event counting. After | | ||
-|| |the initialisation, OUT | | ||
-|| |is initially low, and | | ||
-|| 0 |will remain low until the |Start counting| Hardware gate ||
-|| |counter reaches zero. | value | ||
-|| |OUT then goes high and | | ||
-|| |remains high until a new | | ||
-|| |count is written. See | | ||
-|| |"i_APCI1710_WriteTimerValue" | | ||
-|| |function. | | ||
-|+--------+-----------------------------+--------------+--------------------+|
-|| |Mode 1 is similar to mode 0 | | ||
-|| |except for the gate input | | ||
-|| 1 |action. The gate input is not|Start counting| Hardware trigger ||
-|| |used for enabled or disabled | value | ||
-|| |the timer. | | ||
-|| |The gate input is used for | | ||
-|| |triggered the timer. | | ||
-|+--------+-----------------------------+--------------+--------------------+|
-|| |This mode functions like a | | ||
-|| |divide-by-ul_ReloadValue | | ||
-|| |counter. It is typically used| | ||
-|| |to generate a real time clock| | ||
-|| |interrupt. OUT will initially| | ||
-|| 2 |be high after the | Division | Hardware gate ||
-|| |initialisation. When the | factor | ||
-|| |initial count has decremented| | ||
-|| |to 1, OUT goes low for one | | ||
-|| |CLK pule. OUT then goes high | | ||
-|| |again, the counter reloads | | ||
-|| |the initial count | | ||
-|| |(ul_ReloadValue) and the | | ||
-|| |process is repeated. | | ||
-|| |This action can generated a | | ||
-|| |interrupt. See function | | ||
-|| |"i_APCI1710_SetBoardInt- | | ||
-|| |RoutineX" | | ||
-|| |and "i_APCI1710_EnableTimer" | | ||
-|+--------+-----------------------------+--------------+--------------------+|
-|| |Mode 3 is typically used for | | ||
-|| |baud rate generation. This | | ||
-|| |mode is similar to mode 2 | | ||
-|| |except for the duty cycle of | | ||
-|| 3 |OUT. OUT will initially be | Division | Hardware gate ||
-|| |high after the initialisation| factor | ||
-|| |When half the initial count | | ||
-|| |(ul_ReloadValue) has expired,| | ||
-|| |OUT goes low for the | | ||
-|| |remainder of the count. The | | ||
-|| |mode is periodic; the | | ||
-|| |sequence above is repeated | | ||
-|| |indefinitely. | | ||
-|+--------+-----------------------------+--------------+--------------------+|
-|| |OUT will be initially high | | ||
-|| |after the initialisation. | | ||
-|| |When the initial count | | ||
-|| 4 |expires OUT will go low for |Start counting| Hardware gate ||
-|| |one CLK pulse and then go | value | ||
-|| |high again. | | ||
-|| |The counting sequences is | | ||
-|| |triggered by writing a new | | ||
-|| |value. See | | ||
-|| |"i_APCI1710_WriteTimerValue" | | ||
-|| |function. If a new count is | | ||
-|| |written during counting, | | ||
-|| |it will be loaded on the | | ||
-|| |next CLK pulse | | ||
-|+--------+-----------------------------+--------------+--------------------+|
-|| |Mode 5 is similar to mode 4 | | ||
-|| |except for the gate input | | ||
-|| |action. The gate input is not| | ||
-|| 5 |used for enabled or disabled |Start counting| Hardware trigger ||
-|| |the timer. The gate input is | value | ||

-| | APCI1710_PCI_BUS_CLOCK | For the timer input clock, the PCI | |

-| 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 : unsigned char_ b_BoardHandle : Handle of board APCI-1710 |

-| (0 or 1). |
-| data[1] unsigned char_ b_PCIInputClock : Selection from PCI bus clock|
-| - APCI1710_30MHZ : |
-| The PC have a PCI bus |
