19 / 192 page  SN8F27E60 Series 8-Bit Flash Micro-Controller with Embedded ICE and ISP SONiX TECHNOLOGY CO., LTD Page 19 Version 1.4 Example: Defining Interrupt Vector. The interrupt service routine is following user program. .CODE ORG 0 ; 0000H JMP START ; Jump to user program address. … ORG 8 ; Interrupt vector, 0008H. JMP ISR_WAKE ; Jump to interrupt service routine address. JMP ISR_INT0 JMP ISR_INT1 JMP ISR_T0 JMP ISR_TC0 JMP ISR_TC1 JMP ISR_TC2 JMP ISR_T1 JMP ISR_ADC JMP ISR_SIO JMP ISR_MSP JMP ISR_UART_RX JMP ISR_UART_TX ORG 15H START: ; 0015H, The head of user program. … ; User program. … … JMP START ; End of user program. … ISR_WAKE: ; The head of interrupt service routine. ; Save ACC and 0x80~0x8F register to buffers. … ; Load ACC and 0x80~0x8F register from buffers. RETI ; End of interrupt service routine. ISR_INT0: ; ; Save ACC and 0x80~0x8F register to buffers. … ; Load ACC and 0x80~0x8F register from buffers. RETI ; End of interrupt service routine. … … … … … ISR_UART_TX: ; ; Save ACC and 0x80~0x8F register to buffers. … ; Load ACC and 0x80~0x8F register from buffers. RETI ; End of interrupt service routine. ENDP ; 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~0014H is interrupt vector. 3. User ’s program is a loop routine for main purpose application. |
