Describe the feature request

Since LVGL is more and more used as an desktop app too, I think it's necessary to have a clean application exit event too.
Right now, all example have a while(1) { } in their main function so when you close the app (by clicking the X icon, or Alt+F4 or ...), you're actually leaking all the application objects.

For most of them, it's not important, but som

Is your enhancement proposal related to a problem? Please describe.
access_addr always seems to be of size 4; that should be #defined.
crc_init always seem to be of size 3; that should be #defined.

• The set_mode_X() HIL functions need to support returning an error if hardware does not support that mode or if the implementation cannot put the hardware in to that mode at that time. See for an example where panic is used instead of returning an error https://github.com/tock/tock/pull/2629/files.

CircuitPython version

Adafruit CircuitPython 7.3.0-rc.2 on 2022-05-21; Raspberry Pi Pico with rp2040

Code/REPL

b = (0xFEED).to_bytes(2,"little")
# next line is not correct code
x = int.from_bytes(b, 2, "little")
print(x==0xFEED)

Behavior

C Python raises a TypeError if too many arguments:

int.from_bytes(bytes([0xFE,0xED]), 2, "big")

In PROTECTED mode, the MPU is used to map regions of memory to supervisor- and/or user-accessible memory. Currently, that algorithm is very simple: The entire address range is made accessible in supervisor mode; a single MPU region is used to enable user-mode access in each user memory region.

Each MPU region must bit both of a power-of-two size and with an alignment in memory equal to the si
