Example: Defining Interrupt Vector. The interrupt service routine is following user program.  
.CODE  
ORG  
JMP  
0
; 0000H  
START  
; Jump to user program address.  
ORG  
JMP  
8
; Interrupt vector.  
; 0008H, Jump to interrupt service routine address.  
MY_IRQ  
ORG  
10H  
START:  
; 0010H, The head of user program.  
; User program.  
JMP  
START  
; End of user program.  
MY_IRQ:  
;The head of interrupt service routine.  
PUSH  
; Save ACC and PFLAG register to buffers.  
POP  
RETI  
; Load ACC and PFLAG register from buffers.  
; End of interrupt service routine.

Note: It is easy to understand the rules of SONIX program from demo programs given above. These  
points are as following:  
1. The address 0000H is a “JMP” instruction to make the program starts from the beginning.  
2. The address 0008H is interrupt vector.  
3. User’s program is a loop routine for main purpose application.
