### 4.4. Instruction for internal triggering

This special instruction has `INSN_INTTRIG` as the `insn` member in its instruction data structure. Its execution causes an internal triggering event. This event can, for example, cause the device driver to start a conversion, or to stop an ongoing acquisition. The exact meaning of the triggering depends on the card and its particular driver.

The `data`[0] element of the `INSN_INTTRIG` instruction is reserved for future use, and should be set to `0`.
