5.4.5.1.2. Trigger that Skips Clock Cycles after Hitting Condition

Trigger flow description that skips three clock cycles of samples after hitting condition 1

Code:

State 1: ST1
	start_store
	if ( condition1 )
	begin
	   stop_store;
	   goto ST2;
	end
State 2: ST2
	if (c1 < 3)
	   increment c1; //skip three clock cycles; c1 initialized to 0
	else if (c1 == 3)
	begin
	   start_store;//start_store necessary to enable writing to finish
					 //acquisition
   	trigger;
	end

The figures show the data transaction on a continuous capture and the data capture when you apply the Trigger flow description.
