从键盘读入一个四位的十六进制数，CRT显示等值的二进制数. 由于每个十六进制数位对应4个二进制，所以每读入一个十六进制位后，即可将其对应的4个二进制位依次输出。由于数字‘０’~ ‘９’的ASCⅡ码为30H～39H,字母‘a’～‘f’与 ‘A’～‘F’的ASCⅡ码为61H～66H 与41H～46H ，因此，如果输入的字母为数字‘０’～‘９’，则其低４位即为对应的二进制位；如果输入的字符为字母‘ａ’～‘ｆ’或‘Ａ’～‘Ｆ’，则需要减７，然后通过移位将低４位依次输出。 -Reading from the keyboard into a 4 hexadecimal number, CRT display equivalent binary number. Since each hexadecimal number of the corresponding 4-bit binary, so every time into a hexadecimal places, can be its corresponding 4-bit binary sequence output. Due to the number

片机电子钟的计时脉冲基准是由外部晶振的频率经过12分频后提供，采用内部的定时/计数器来实现计时功能。所以，外接晶振频率精确度直接影响电子钟计时的准确性。 -Machine electronic time clock pulse baseline is by an external crystal oscillator frequency, after 12 minutes after the frequency, using an internal timer/counter to achieve the timing function. Therefore, the external crystal frequency accuracy of a direct impact on the accuracy of the electronic time clock.
