Where are fields to define a I2C PAD configuration for imxrt1060 documented?

I'm developing an application on a Teensy 4.0 using the arm cortex m7 processor that incorporates imxrt1060 functionality. In order to set the pad to support a i2C port I need some detailed information  on the fields used to define the pad configuration..

The statement I need to configure is

#define PAD_CONFIG IOMUXC_PAD_DSE(4) | IOMUXC_PAD_SPEED(1) | IOMUXC_PAD_PKE | IOMUXC_PAD_PUE | IOMUXC_PAD_PUS(3) | IOMUXC_PAD_ODE | IOMUXC_PAD_HYS

I've searched and can't find detailed information on fields like DSE, SPEED, and PUS. What do the subscripts mean? What do the PKE, PUE, PUS fields mean and now should they be set when using an external pull up resistor. I'm sure that these values are documented. I just can't find where. Any help would be appreciated.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you to refer to the RM, you can find the meaning of the below subscript.

#define PAD_CONFIG IOMUXC_PAD_DSE(4) | IOMUXC_PAD_SPEED(1) | IOMUXC_PAD_PKE | IOMUXC_PAD_PUE | IOMUXC_PAD_PUS(3) | IOMUXC_PAD_ODE | IOMUXC_PAD_HYS

I also found ii in this application note on page 16.
