6.5.1.4 Bit12-Bit10: External Trigger Control 

 

The operation steps of 

post-trigger

 are given as follows: 

 

Step 1: Disable all external trigger 
Step 2: Set the pacer rate of timer-1 
Step 3: Clear FIFO & disable timer-1 
Step 4: Wait until external trigger signal to enable timer-1 

Step 5: Fetch N data(N=End-Start) 
Step 6: Stop all timer 
 
 

 

The operation steps of 

pre-trigger

 are given as follows: 

 
Step 1: Disable all external trigger 

Step 2: Set the pacer rate of timer-1 

Step 3: Clear FIFO & enable timer-1 

Step 4: Circular-fetch N-data until external trigger   

signal to disable timer-1 (N=End-Start) 

Step 5: Stop all timer 

NOTE: The circular-fetch operation is performed by software 

 

 

The operation steps of 

middle-trigger

 are given as follows: 

 
Step 1: Disable all external trigger 
Step 2: Set the pacer rate of timer-1 

Step 3: Clear FIFO & enable timer-1 

Step 4: Circular-fetch N-data until external trigger signal (N=End-Start) 

Step 5: Fetch more N2-data & stop timer-1 
Step 6: Stop all timer 

NOTE: The circular-fetch operation is performed by software 
 

 

Note 1: The external trigger operation must use with the MagicScan controller. The software 

flowchart of external trigger is given in next page. 

Note 2: The post-trigger operation can use all MagicScan function. 
Note 3: The user can’t enable MagicScan HI/LO alarm and digital filter function in the pre-trigger & 

middle-trigger operation.
