Force an hard reset to RT1051

In the Ref Man I read that there are two types of reset: POR and cold.

The difference seems to be related to some peripherals that are not reset, in the case of cold reset, especially IOMUX.

If, while the micro is running, the POR_B pin is driven low, what kind of reset is it?

During the time that POR_B is kept low, are the micro pins kept low impedance on high?
I would like to find a way to force an "hard" reset, where all the peripheral are reset, and that makes sure to put all pins in high impedance (e.g. GPIO input without pull up/down) in particular during POR_B kept low.


best regards
