8253clock
- 本实验利用8253做定时器,用定时器输出的脉冲控制8259产生中断 在8259中断处理程序中,对时、分、秒进行计数,在等待中断的循 环中用LED显示时间。 8253用定时器/计数器1,8253片选接CS4,地址为0C000H。8253时钟 源CLK1接分频电路的F/64输出。分频器的Fin接4MHz时钟。8253的 GATE1接VCC。 8259中断INT0接8253的OUT1,片选接CS5,地址为0D000H。 显示电路的KEY/LED CS 接CS0

interrupts
- This example application demonstrates the interrupt preemption and tail-chaining capabilities of Cortex-M3 microprocessor and NVIC. Nested interrupts are synthesized when the interrupts have the same priority, increasing priorities, and decreas
