Are there any issues with the UniPHY LPDDR2 IP address and command pinout ?
Description
In the 12.0 version of the External Memory Interface Handbook : Volume 2 Chapter 3 "Planning Pin and FPGA Resources" Table 3-14 has incorrect information for the Address and Command Pinout.
Resolution
It states the address and command pins can be placed on "Any user I/O pin".
The correct placement details are "Place all the address and command pins in a single x8/9 DQ/DQS group".
12 pins are required : mem_ca[9:0], mem_cke[0] and mem_cs_n[0]
This will be corrected in a future version of the EMI Handbook.
