13.4.2 Trigger events features
The TGS has the capability to generate up to eight trigger events. Each trigger event has the following
characteristics:
• The generation of the trigger event is sequential in time.
• The Triggers List uses eight 16-bit double-buffered registers.
• On each Master Reload Signal (MRS), the new Triggers List is loaded.
• The Triggers List is reloaded on a MRS occurrence, only if the reload enable bit is set.
13.4.3 Trigger generator subunit (TGS)
The trigger generator subunit has the following two modes:
• Triggered mode: each event source for the incoming signals can generate up to eight trigger event
outputs. For the ADC, a commands list is entered by the CPU, and each event source can generate
up to eight commands or streams of commands.
