Description: 用8253作为秒定时器，每0.1秒8253周期定时中断，8253的OUT0接到8259的IRO端，8259向8086产生中断请求，中断类型号为08H。程序开辟秒、分、小时、寄存器单元，秒寄存器每记数满60，分寄存器值加1，同时秒寄存器清0。分寄存器每记数满60，小时寄存器值加1，同时分寄存器清0。秒、分、小时寄存器中的二进制值转换成BCD码后，送6位LED数码管显示。-Using 8253 as a second timer, 0.1 seconds per cycle timer interrupt 8253, 8253 received OUT0 of the IRO-end 8259, 8259 to 8086 generate an interrupt request, interrupt type number 08H. Procedures for opening seconds, minutes, hours, register unit, the number of seconds register each entry age of 60, sub-register value plus 1, and 0 seconds register ching. Sub-registers each counting the age of 60, hour register value plus 1, while sub-register-ching 0. Seconds, minutes and hours registers in the binary value into BCD code, to send six LED digital tube display.

Description: 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，地址为08000H。-In this study, the use of 8253 to do the timer, using timer pulse output control 8259 generates an interrupt in 8259 interrupt handler, for hours, minutes and seconds count, waiting for interruption through ring using LED display time. 8253 with the timer/counter 1,8253 chip select access CS4, address 0C000H. 8253 clock source CLK1 of the F/64 then divider circuit output. Fin then 4MHz clock divider. 8253' s GATE1 then VCC. 8259 interrupt INT0 then 8253' s OUT1, chip select access CS5, address 0D000H. Display circuit of the KEY/LED CS access CS0, address 08000H.
