START

; 0000H

; Jump to user program address.

; Interrupt vector.

; 0008H, Jump to interrupt service routine address.

; 0010H, The head of user program.

; User program.

; End of user program.

;The head of interrupt service routine.

; Save ACC and PFLAG register to buffers.

; Load ACC and PFLAG register from buffers.

; End of interrupt service routine.

; End of program.

’ 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.
