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! !
