说明：  STC8F2K64S2系列单片机提供16个中断请求源，分别是：外部中断0中断（int0）、定时器0中断（timer0）、外部中断1中断（int1）、定时器1中断（timer1）、串行端口1中断（uart1）、低压检测中断（lvd）。，串行端口2中断（UART2），串行外围接口中断（SPI），外部中断2中断（INT2），外部中断3中断（INT3），定时器2中断（Timer2），外部中断4中断（INT4），定时器3中断（Timer3），定时器4中断（Timer4），比较器内部PT（CMP），I2C总线中断。除了外部中断2、外部中断3、定时器2中断、定时器3中断、定时器4中断和比较器中断固定是最低优先级中断外，所有其他中断都有四个可设置的中断优先级。(STC8F2K64S2 series single chip microcomputer provides 16 interrupt request sources, which are: external interrupt 0 interrupt (INT0), timer 0 interrupt (Timer0), external interrupt 1 interrupt (INT1), timer 1 interrupt (Timer1), serial port 1 interrupt (UART1), low voltage detection interrupt (LVD), serial port 2 interrupt (UART2), serial peripheral interface interrupt (SPI), external interrupt 2 interrupt (INT2), external interrupt 3 interrupt (INT3), Timer 2 interrupt (Timer2), external interrupt 4 interrupt (INT4), timer 3 interrupt (Timer3), timer 4 interrupt (Timer4), comparator interrupt (CMP), I2C bus interrupt. Except that the external interrupt 2, the external interrupt 3, the timer 2 interrupt, the timer 3 interrupt, the timer 4 interrupt and the comparator interrupt fixed are the lowest priority interrupts, all the other interrupts have four interrupt priorities that can be set.)

本程序用于测试实时时钟模块SD2000系列功能之一:四种中断功能 程序功能如下： 1.在SD2000试验板上显示实时时间的小时和分钟? 2./INT1 到指定时刻时输出低电平. 3./INT2输出固定频率32768HZ. 4.测试每分钟边沿中断输出(INT MODE3)和每分钟固定中断输出(INT MODE4)功能-procedures used to test the real-time clock module SD2000 series of functional one : four interrupts functions of the program are as follows : 1. The SD2000 board real-time test of time 2./INT1 hours and minutes to the designated low-level output at the moment. 3./INT2 32768HZ fixed frequency output. 4. testing every minute edge interrupt output (INT MODE3) per minute and fixed interrupt output (INT MODE4) function
