SEQuencer

SEQuencer signals output (trigger) when up to 4 events occur in a sequential order or when a up to 4 events occur in a non-sequential order (SW1 & SW2 & SW3 & SW4). SEQuencer is by default disabled.

Sequencer match - The sequencer is equipped with a 32-bit counter (default disabled), which outputs the event signal when the  sequential or non-sequential event occurs the specified number of times.

Post delay count - Counter can act as a delay unit (‘Post delay count’ selection), which uses system clock as the count source and waits until the specified count value has elapsed after a sequential or non-sequential event occurs before outputting the event signal.

 

 

Sequencer configuration

The sequencer can be configured to act either as a four-stage (SW1 -> SW2 -> SW3 -> SW4), three-stage (SW2 -> SW3 -> SW4), two-stage (SW3 -> SW4) or one-stage (SW4) sequential unit. Four of the available Instruction and Data events are used as the ON conditions of the four-stage sequential unit’s switches, SW1 to SW4, respectively, and one event detection signal is used as the clear condition (CLR) for the switches of all four stages. If an event with a clear condition (CLR) is detected before an on condition is detected for the last stage of the sequential unit, all switches SW1 to SW4 are cleared.

 

1. Enable the SEQuencer in the Trigger Configuration dialog.

2. Click on the "number" button in the Execution or Data section to open the Event dialog.

3. Select stages.
