clk: 标准时钟信号,本例中,其频率为4Hz;
clk_1k: 产生闹铃音、报时音的时钟信号,本例中其频率为1024Hz;
mode: 功能控制信号;为0:计时功能;
为1:闹钟功能;
为2:手动校时功能;
turn: 接按键,在手动校时功能时,选择是调整小时,还是分钟;
若长时间按住该键,还可使秒信号清零,用于精确调时;
change: 接按键,手动调整时,每按一次,计数器加1;
如果长按,则连续快速加1,用于快速调时和定时;
hour,min,sec :此三信号分别输出并显示时、分、秒信号,
皆采用BCD码计数,分别驱动6个数码管显示时间;
alert: 输出到扬声器的信号,用于产生闹铃音和报时音;
闹铃音为持续20秒的急促的"嘀嘀嘀"音,若按住"change"键,
则可屏蔽该音;整点报时音为"嘀嘀嘀嘀-嘟"四短一长音;
LD_alert: 接发光二极管,指示是否设置了闹钟功能;
LD_hour: 接发光二极管,指示当前调整的是小时信号;
LD_min: 接发光二极管,指示当前调整的是分钟信号。-If long press, the continuous rapid plus 1 for quick adjustment and timing,
Hour-by-hour, min, SEC: this three signal output and display when respectively, minutes and seconds signal,
All USES BCD counter, respectively driven six digital pipe display time,
Where the signal to the speaker: output, used to produce make primitive and strike the sound,
Make businessis about for lasts 20 seconds the urgent "di di di" sound, if hold "information" key,
Then can shield the sound, Integral point to announce the sound as "di di di di- du" four short a drawl,
LD_alert: connect the light emitting diode, instruction set the alarm clock function whether
LD_hour: connect the light emitting diode, instructions, the current is to adjust the hour signal,
LD_min: connect the light emitting diode, instructions, the current is to adjust the minutes signal.
