Hi everyone,
I configured the SSU(SPI) driver as slave device in my SH7286.I tried to receive data sent from R8C controller(configured as Master).Problem i am facing is
SH7286 device failed to receive data.It (Status register) shows Conflict error even without the Receive buffer full flag is set.What are the possible reasons for such a conflict error???Can anyone help me in this issue.?
Thanks

Click to expand...

One possible reason is CS line will be driven high by the Master.Next thing to be checked is Whether SH7286 is configured as slave.If it is master and R8C tried to drive clock CE occurs.
 
Thank u vivek...CE problem is no more there.
