在没有硬件看门狗的系统以及一些对单片机I/O口线状态高度敏感的系统中,软复位功能相当重要。标准MCS-51以及很多常见的51内核单片机没有提供“软复位”方法。本文分别以51asm子程序和C51函数的形式,为MCS-51单片机系统提供完善的“软复位”方法。
In systems without hardware watchdogs and some systems that are highly sensitive to the microcontroller I / O line-of-line status, the soft-reset feature is important. The standard MCS-51 and many common 51-core microcontrollers do not provide a “soft reset” method. This article respectively 51asm subroutine and C51 functions in the form of MCS-51 SCM system to provide a complete “soft reset” method.
