After reset, the driver program will attempt to clear error counts and release the FS1B pin, so the situation depicted in the diagram will not occur.What was the problem?
做到哪一步了?RSTB release了?然后就是写一次WD 退出INIT阶段在256ms以内如果写错了或者超过了256ms才去写RSTB也会reset一下再次给机会去写WD进入下一个阶段,然后再继续feed WD 去减少FAULT ERROR COUNTER 值,如果期间的每一次feed WD错误都会导致fault errorcounter的增加这样就不会release FS1B/FS0B
