看门狗应用
    适用型号:  STC12C2052AD 系列
Symbol 符号 Function 功能
WDT_FLAG    When WDT overflows, this bit is set. It can be cleared by software.
          看门狗溢出标志位,当溢出时,该位由硬件置 1,可用软件将其清 0。
EN_WDT
Enable WDT bit. When set, WDT is started
看门狗允许位,  当设置为“1 ”时,看门狗启动。
CLR_WDT
WDT clear bit. When set, WDT will recount. Hardware will automatically clear
            this bit.
看门狗清“0 ”位, 当设为“1 ”时,看门狗将重新计数。硬件将自动清“0 ”此位。
IDLE_WDT
When set, WDT is enabled in IDLE mode. When clear, WDT is disabled in IDLE mode
看门狗“IDLE ”模式位, 当设置为“1 ”时, 看门狗定时器在“空闲模式”计数
                               当清“0”该位时, 看门狗定时器在“空闲模式”时不计数
PS2, PS1, PS0 Pre-scale value of Watchdog timer is shown as the bellowed table:
            看门狗定时器预分频值,如下表所示
The WDT period is determined by the following equation 看门狗溢出时间计算
看门狗溢出时间 = (12 x Pre-scale x 32768) / Oscillator frequency
设时钟为 12MHz:
看门狗溢出时间 = (12 x Pre-scale x 32768) / 12000000 = Pre-scale x 393216 / 12000000
