Regarding i.MX6SDL IOMUX SPEED field setting.

[satoshishimoda]

Hi community,

I have a question about i.MX6SDL IOMUX pad control.

Please see "SPEED" field in chapter 37.4.212 in IMX6SDLRM Rev.2.

Would you let me know whether there is a difference between the following settings.

01 MEDIUM — 100 MHz, if SRE=1: 100MHz @ 1.8V, 150MHz @ 3.3V

10 MEDIUM — 100 MHz, if SRE=1: 100MHz @ 1.8V, 150MHz @ 3.3V

Best Regards,

Hi Igor,

I checked Table 29-9, but I did not find the difference between SPEED=01b and SPEE=10b.

"Operating Frequency (MHz)" values when SPEED=01b and when SPEED=10b seem to same value regardless of the settings of DSE, SRE, and OVDD.

Hi Satoshi

you are right : settings are the same.

You can ignore my previous remark about exceptions.

Best regards
