i.mx6 DISP0_DATxx Output Impedance

[djb33]

I was wondering if anyone knows where I can find DISP0_DATxx single-ended output impedance information for the i.mx6?

I've looked in the i.mx6 Techinical Datasheet (IMX6DQAEC.pdf) under 'Electrical Characteristics'->'Image Processing Unit (IPU)' and found nothing.

The other peripherals 'LVDS' and 'MIPI D-PHY' both contain the 'Singled-Ended Output Impedance' information, but the display port's cannot be located.

Any help would be greatly appreciated.

Thanks.

Hi K R

for these pins please use

sect.4.8.1 GPIO Output Buffer Impedance IMX6DQCEC

Igor,

    It seems upon verifying this in software under the register:

IOMUXC_SW_PAD_CTL_PAD_DISP0_DATA00

found in: IMX6DQRM

We get a value of '000'  for the DSE (drive strength field). Can I assume that this is the correct register and field?

Also, we are outputting data on this pin, but still have a value of high impedance for the drive strength. Is this normal?

Thanks.

Hi K R

yes DSE is correct setting for impedance.

You can check with other pads and configure as GPIO

just for test.
