Question about Memory Address Drive Strengs for i.MX7

Dear All,

We adjust the drive strengh for the memory address using CAADRDRVRDS in DDR_PHY_DRVDS_CON0 register.

However, the description in i.MX7 reference manual is only CA[9:0].

PRI_20171120-212449.png

* Page 2346 in i.MX 7Dual Applications Processor Reference Manual, Rev. 0.1

Which register does the drive strengs for bits higher than CA[9] use?

Best Regards,

George

Hello,

 bit field CAADRDRVRDS of DDR_PHY_DRVDS_CON0 controls all i.MX7 DRAM address

lines.

Have a great day,
Yuri
