TrigMode Parameter

The IMMEDIATE option means that the initial TE is equivalent to SAS. As soon as the acquisition sequence is awakened (generally, when the application sets the ChannelState parameter to ACTIVE), the first acquisition phase takes place.

The HARD option means that the TE occurs upon reception of a valid transition on a hardware line while the channel is armed. The hardware trigger line involved is specified by TrigLine, TrigCtl, TrigEdge and TrigFilter.

The SOFT option means that the TE occurs when the application sets the ForceTrig parameter while the channel is armed.

The COMBINED option means that the TE occurs indifferently for conditions described for HARD and SOFT.

The TrigMode parameter can be modified under application control without returning the channel to the IDLE state.
