MCS-96单片机要用PWM产生锯齿波，应使PWM寄存器中的值线性增加，那么在PWM输出端将得到宽度线性增加的脉冲波，经滤波后，便可得到锯齿波。-MCS-96 microcontroller with PWM have Sawtooth, PWM register should be the value of linear increase, then the PWM output will be increased linearly width of the pulse wave, After filtering, it will be Sawtooth.

cdecl函数调用，了解printf这样的函数调用，对比stdcall会更清楚。-cdecl function call, to understand such a function call printf, compared stdcall will be clearer.

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
