### 4. Functionality
Operating Principle:
The PIO‑48D(CB)H uses two Intel 8255‑compatible I/O controllers operating in Mode 0 (simple I/O). Each controller provides 24 I/O lines divided into A, B, and C ports. Ports can be individually configured for input or output via control words.
Use Cases & Applications:
- Industrial automation and machine control
- Data acquisition and monitoring systems
- Laboratory instrumentation
- Embedded test and measurement applications
- Portable control systems using laptops with CardBus slots
Compatibility:
- Operating Systems: Windows 98/Me/2000/XP and Linux (Red Hat, TurboLinux, etc.)
- Programming Languages: Visual C/C++, Visual Basic, Delphi, Builder, gcc, Kylix
- Software Interfaces: API‑PAC(W32), API‑DIO(LNX), ACX‑PAC(W32)BP/AP ActiveX components, and VI‑DAQ for LabVIEW
Digital Filter Operation:
The filter samples input levels at a fixed clock rate (8 MHz). If the signal remains stable for the configured filter time, the input state is accepted; otherwise, transient changes are ignored. Filter time is set by a 5‑bit value (0–20) corresponding to 0.25 µs to 131.072 ms.
Interrupt Control:
Each input bit can generate an interrupt on a rising or falling edge. Mask bits enable/disable interrupts per bit. Status bits indicate which input triggered the interrupt. All mask and status bits reset to 0 at power‑on.
