Hello,
let me raise a few questions about TRM section 20.2.6 - Data Bus Parking.
1. The one exception to this behavior occurs after performing an asynchronous read operation while the EMIFA is in the self-refresh state.
It's not quite clear to me whether you refer to SDRAM or ASYNC mode, or both.
2. External pull-ups, such as 10kΩ resistors, should be placed on the 16 EMIFA data bus pins (which do not have internal pull-ups) ..
You say that EMIFA data bus does not have internal pulls; however, CP[17] should serve well here. What am I missing?
Many thanks,
Milan
