### 4. Functionality

Operating Principle:
The PCI-7300A provides high-speed digital I/O through two 16-bit ports (A and B). Each port can be independently configured as input or output. Data is buffered via onboard FIFOs and transferred to/from host memory using bus-mastering DMA, minimizing CPU overhead.

Supported Modes:
1. Internal Clock Mode:
Data sampled/output at fixed internal rates (10/20 MHz or timer-based).
2. External Clock Mode:
Synchronization with external strobe (DI_REQ/DO_ACK).
3. Handshaking Mode:
REQ/ACK protocol ensures reliable data transfer without loss.
4. Burst Handshaking Mode:
High-speed, low-latency transfer allowing up to 4 samples post-ACK deassertion.
5. Pattern Generation Mode:
Repetitive digital output patterns at programmable rates.

Applications:
- High-speed data acquisition and digital pattern capture
- Logic analysis and digital waveform generation
- Automated test equipment (ATE)
- Parallel digital communication interfaces
- Real-time control and simulation systems
- Interface to high-speed A/D or D/A converters

Compatibility:
- PCI 2.2 compliant (5V signaling)
- Compatible with ADLINK terminal boards (DIN-100S, DIN-502S)
- Supported by ADLINK’s DAQPilot, PCIS-DASK, and DAQBench software suites
