Does the i.MX RT1060 / Teensy 4.x support Bit-Banding?

The i.MX RT1060 is a Cortex M7 microcontroller. **Cortex M7 microcontrollers do not support bitbanding.**Hence, the i.MX RT106x series (including the Teensy 4.0 and 4.1 boards) do not support bitbanding. See this ARM forum post for more details.
