Hi community,
I have a question about i.MX6DQ ODT.
Please see IOMUXC_SW_PAD_CTL_GRP_TERM_CTLx register in IMX6DQRM Rev.1.
These registers have "ODT" fields to determine the ODT values.
On the other hand, please see MMDCx_MPODTCTRL register (chapter 44.12.38).
These have "ODTx_INT_RES" fields to determine the ODT values, also.
Then, which registers have a priority to setting ODT value?
According to the following comment in IMX6D ODT, I guess MMDCx_MPODTCTRL have a priority, is this correct?
"3. It is recommended to use only MMDC_MPODTCTRL register to configure ODT of i.MX6."
Best Regards,
Satoshi Shimoda

Hi Satoshi,
these registers are working independently from each other (no priority).
And yes:
"3. It is recommended to use only MMDC_MPODTCTRL register to configure ODT of i.MX6."
