11. 2 e Operation Theorem Usually the timer trigger is used under this mode therefore the sampling rate is fixed The method also utilizes the minimum CPU resources because it is not necessary to be the highest priority The other benefit is this method will not use hardware interrupt resource Therefore the interrupt is reserved for system clock or emergency external interrupt request The FIFO half full polling method is the most powerful A D data transfer mode EOC Interrupt Transfer The PCI 9113 provides traditional hardware end of conversion EOC interrupt capability Under this mode an interrupt signal is generated when the A D conversion is ended and the data is ready to be read in the FIFO It is useful to combine the EOC interrupt transfer with the timer pacer trigger mode After A D conversion is completed the hardware interrupt will be inserted and its corresponding ISR Interrupt Service Routine will be invoked and executed The ISR program can read the converted data This method is most suitable for data processing applications under real time and fixed sampling rate FIFO Half Full Interrupt Transfer Sometimes the applications do not need real time processing but the foreground program is too busy to poll the FIFO data The FIFO half full interrupt transfer mode is useful for the situation mentioned above In addition as the external A D trigger source is used the sampling rate may be not easy to predict and then the meth
