6.34 _9113_AD_FFHF_INT_Start

@ Description
This function is used to initial and start up the interrupt transfer by
using AD FIFO Half-Full Interrupt Transfer Mode. This function could
perform A/D conversion N times with interrupt data transfer by using
pacer trigger. It takes place in the background and will not stop until
the N-th conversion has been completed or your program execute
_9113_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 _9113_AD_FFHF_INT_Status(). The function can
perform on single A/D channel (autoscan is disabled) or multiple
A/D channels (autoscan is enabled) with 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 MS-DOS Borland C++ library supports
just one PCI-9113A card and provides only one ISR (interrupt
service routine) for processing the interrupt events. If multi-9113A
cards and multi -isr is necessary, users can modify this library for
your own purpose.
