srio lcb ltid



lsu0的影子寄存器配置为4

使用DIO方式,对lsu0进行SWRITE操作

第1次:LTID =0,reg6^LCB = 1,影子寄存器^LCB=1;

第2次:LTID =1,reg6^LCB = 1,影子寄存器^LCB=1;

第3次:LTID =2,reg6^LCB = 1,影子寄存器^LCB=1;

第4次:LTID =3,reg6^LCB = 1,影子寄存器^LCB=1;

第5次:LTID =0,reg6^LCB = 0,影子寄存器^LCB=0;

第6次:LTID =1,reg6^LCB = 0,影子寄存器^LCB=1;这次错误reg6^LCB !=影子寄存器^LCB,请问这是什么原因?
