应该不是IIC中断吧,它在cpu.c文件中,而且描述中说明:The method services unhandled interrupt vectors.This method is internal. It is used by Processor Expert only.
应该如何看它的地址?在Assembly窗口中么?作者: strongchen 时间: 2007-11-28 11:08
在QG8的spec中关于IICIF是这么写的
IIC Interrupt Flag — The IICIF bit is set when an interrupt is pending. This bit must be cleared by software, by writing a one to it in the interrupt routine.
为了清除这个标志位,还要向这一位写"1"??感觉很难理解,还是spec上写错了?作者: strongchen 时间: 2007-11-30 10:25
