\section{General description}
An FMC3 is a mezzanine card in FMC format, containing four identical analog output channels. Each channel has a 10MS/s 16-bit DAC with an output range of +/-10V. In addition, the card has three trigger inputs (start, pause and abort) and one external clock input. These inputs are common to the four analog channels.

The FMC3 has two trigger inputs. A start and a pause input. They can be used in many different ways.
The first and simplest case uses only the start input. The selected waveform is generated when a start pulse arrives. Generation continues until the end of the waveform.
\begin{comment}
Then the abort input can be used to stop a waveform generation. This input is mainly used for safety reason. It allows to stop the waveform generation at the end of a accelerator cycle, to make sure that the next cycle waveform can start properly. Even if there was a problem during generation.
\end{comment}
The "pause" trigger input is used to suspend the waveform generation. After a pause pulse, a new start pulse is needed in order to continue waveform generation.
Moreover, in vector mode, it is possible to program a pause inside a waveform. This is done by means of a special vector called "internal pause". To continue the waveform generation a start pulse is needed, as for the pause trigger input.
