MEGA8芯片编程的注意事项：
1）、如果晶振被编程为外部时钟，此时只有使用外部有源晶振才可重新对MEGA8进行编程。
2）、如果用户只有串行编程设备，请不要将RESET功能禁止，否则只有使用并行高压编程
才能重新恢复。-Synthesis of experimental electronic music MEGA8 source. MEGA8 chip programming note: 1), if the crystal has been programmed for external clock, this time only the use of an external crystal can be re-active MEGA8 program. 2), if the user equipment only serial programming, please do not prohibit the RESET function, otherwise only the use of parallel high-voltage programming can be re-instituted.
