executing this function, the internal AD trigger is disable and the AD timer
is stopped. The function returns the number of the data which has been
transferred, no matter whether if the AD interrupt data transfer is stopped
by this function or by the _9112_AD_INT_Stop() itself.
@ Syntax
Visual C++ (Windows-95)
int W_9112_AD_INT_Stop(int card_number, int * count)

Long
C/C++ ( DOS)

5.25 _9112_AD_Timer
u Description
This function is used to setup the Timer #1 and Timer #2.
Timer #1 & #2 are used as frequency divider for generating constant A/D
sampling rate dedicatedly. It is possible to stop the pacer trigger by
setting any one of the dividers as 0. Because the AD conversion rate is
limited due to the conversion time of the AD converter, the highest
sampling rate of the PCI-9112 can not exceed 100 KHz. The
multiplication of the dividers must be larger than 20.
