Disable/enable PCM-3718 card's interrupt generation
0 Disables the generation of interrupts. No interrupt signal
will be sent to the PC bus.
1 Enables the generation of interrupts.
If DMAE = 0, the PCM-3718 card will generate an inter-
rupt when it completes an A/D conversion. Use this set-
ting for interrupt-driven data transfer.
If DMAE = 1, the PCM-3718 card will generate an inter-
rupt when it receives a T/C (terminal count)
signal from the PC's DMA controller, indicating that a
DMA transfer has been completed. Use this setting for
DMA data transfer. The DMA transfer is stopped by the
interrupt caused by the T/C signal. See DMAE below.
