| Abstract: | With considering unable-ending cycle in the process of practical use of single chip microcomputer system, the ways of avoiding programs are discussed in single chip microcomputer going into unable-ending cycle by using hardware watchdog technology when single-chip-microcomputer system is disturbed. The high and dependable electric circuit MAX815 is introduced for the microprocessor with supervising and controlling for at the same time having the watchdog and detect power function, and its application in the single chip microcomputer system is expounded detailedly. |
