### 4. Functionality
The CNT‑3204MT‑LPE functions as a high‑precision pulse counter interface between external sensors and a host PC. It counts incoming pulse trains from encoders, linear gauges, or other pulse‑output devices. Each channel can operate independently in up/down or quadrature mode, allowing simultaneous measurement of multiple axes or signals.
Typical Use Cases:

Operation:
- External pulse signals (A/B/Z) are input to LVTTL terminals.
- The board counts pulses according to configured mode (up/down, quadrature, gated).
- Digital filters remove noise and chattering.
- Count values can trigger interrupts or output pulses when matching preset thresholds.
- Bus master DMA transfers sampled data directly to PC memory for real‑time processing.
- Control inputs/outputs manage start, stop, preset, and zero‑clear operations.
