3.7 Operating Modes
The PCIe-7360 supports four different modes for acquisition and
generation operation, including software polling, continuous,
handshake, and burst handshake mode..
Polling Mode (Single Read/Write)
The PCIe-7360 supports a software polling mode to read or write a
single chunk of data via a software command. That is, the 32-bit
high-speed I/O lines can be used as a static I/O. The data width
can be 8-bit, 16-bit, 24bit, or 32-bit.
DI DMA in Continuous Mode
For the DI pattern acquisition operation in continuous mode,
PCIe-7360 card can acquire input data from external devices at a
specific sampling clock rate (DI sampled clock). DI sample clock
