C51语言的HD7279驱动程序-the HD7279 C51 Driver

键盘扫描算法有很多中，这个程序在IAR编译器下，用C语言描述了其中一种算法-Keyboard scan algorithm has a lot in this process in the IAR compiler, using C language to describe an algorithm which

用于手持时钟受时，时钟芯片的工作稳定性，以D18B20温度传感器的采集，微调时钟芯片的内置电容，改变震荡频率-For hand-held by the clock, the clock chip of job stability to temperature sensor D18B20 collection, fine-tuning of the built-in clock chip capacitors to change the vibration frequency

x5045有四种功能：分别是上电复位、看门狗定时器、电源电压监控和块锁保护串行eeprom的功能， 该程序通过改变控制寄存器的参数可以实现看门狗定时器监视电压和设置保护rom区，每次复位后 地址计数器都是该区的首地址（个人观点），即断点地址。 问题：其实对该芯片的应用还是很模糊-x5045 four functions : the reduction of electricity, watchdog timer, Supply voltage control and protection block serial eeprom lock function, The procedure by changing the parameters of control register can be achieved watchdog timer and set up surveillance voltage protection rom, After each reset address counter area is the first address (personal view), breakpoint address. Question : In fact, the application of this chip is still very fuzzy! !
