programmable clock

A watchdog timer and its prescaler are also provided to improve the microcontroller anti-interference ability. A Real Time Clock/ Counter with Programmable Prescaler of Microcontroller

此外，通过备有监视计时器及其定标器可以有效地提高微机系统的抗干扰能力。备有可编程预定标器的单片机实时时钟/计数器

Through the programmable logic device ( PLD), the first-in first-out ( FIFO)'s four precise clock and write enabling signals can be achieved, thus the accuracy of the whole system and flexibility of the time delay are increased.

通过PLD能够得到FIFO4路精确的时钟和读写使能信号，从而提高了整个系统的工作时钟精确度和延时的灵活性。
