5.36 _9114_AD_INT_Start
@ Description
This function is used to initial and startup the AD EOC (end-of-conversion)
interrupt. This function could perform A/D conversion N times with interrupt
data transfer by using pacer trigger. It takes place in the background and w ill
not stop until the N -th conversion has been completed or your program
execute _9114_AD_INT_Stop() function to stop the process.
After executing this function, it is necessary to check the status of the operation
by using the function _9114_AD_INT_Status(). The function can perform on
single A/D channel (autoscan is disabled) or multiple A/D channels
(autoscan is enabled) with a fixed analog input range.
Note: The interrupt mode provided in this function is internal timer
source, therefore you must specify c1 & c2 as calling this function.
In addition, this function in DOS library supports just one
PCI-9114 card and provides only one ISR (interrupt service
routine) for processing the interrupt events.

@ Argument
cardNo: the card number of PCI-9114 card initialized.
auto_scan: 0: autoscan is disabled.
1: autoscan is enabled.
ad_ch_no: A/D channel number.
If the auto_scan is set as enabled, the selection
sequence of A/D channel is: 0, 1, 2, 3, ...,
