i.MX 8M Mini - GPIO current capability

I need to know how much current the GPIO can source and sink.

 

For example, pins P108 and P109 (GPIO_0, GPIO_1).

 

The datasheet says the output voltage of the pins was tested at 9.6 mA and held 1.8V (section 3.5, table 21).

But then I see the data sheet says the PVCCx1P8 says 3mA max but I'm not sure what "GPIO pre driver" means.

 

Thank you for your help.

Thank you for your response, but I am still a bit unsure of what you're saying.

Hi, 

    First think, all the pin are categorised into GPIO label(From table 7) and digital I/O are categorised into GPIO pre-driver (PVCC). It's operations range from 1.65 to 1.95 volts 3mA. But table no21 mentioned,  all the peripheral which is classified in table 7
