Hi,

I'm Working on the Serial Wire Debugger Protocol, here my problem is when i read the IDCODE register it's returned value is fine but reading of the another register (CTRL/STAT) is returned that ACK Fault but my packet request formation and reading style all are fine.

I'm following the process as per data sheet and verified it also, but it's correct can any one explain about this problem.

Thanks & Regards,
Chandu.Kurapati,
Embedded Software Design Engineer.
