imx6 Solo GPIO configuration to 1.8 volts

[ameerhamza]

Dear all,

I have a question regarding GPIO for imx6 solo, is there any way if we could configure GPIO pin to below 2 volts or 1.8 volts. In Reference manual, IOMUXC_SW_PAD_CTL_PAD_x register i can see DSE field i.e ( Dual/Single voltage: 235/260 Ohm @1.8V, 247/157 Ohm @3.3V)  . Basically i need to connect GPIO to a device which works below 2 volts but i dont know how to configure to below 2 volts or 1.8 volts exactly as mentioned. Looking forward for response.

Thanks,

Hamza.

Hi Hamza

this part has not  bit22 LVE as for example i.MX6SL i.MX6SL IOMUXC_SW_PAD_CTL_PAD_KEY_COL1 

so only way is to use appropriate voltage for power domain, like NVCC_GPIO.

Best regards
igor
