Interrupt related functions
---------------------------
Disable interrupt requests.
Returns the previous IRQ state: ``False``/``True`` for disabled/enabled IRQs
respectively. This return value can be passed to enable_irq to restore
the IRQ to its original state.
.. function:: disable_irq()
.. function:: enable_irq(state=True)
Disable interrupt requests.
Returns the previous IRQ state: ``False``/``True`` for disabled/enabled IRQs
respectively. This return value can be passed to enable_irq to restore
the IRQ to its original state.
Enable interrupt requests.
If ``state`` is ``True`` (the default value) then IRQs are enabled.
If ``state`` is ``False`` then IRQs are disabled. The most common use of
this function is to pass it the value returned by ``disable_irq`` to
exit a critical section.
.. function:: enable_irq(state=True)
Enable interrupt requests.
If ``state`` is ``True`` (the default value) then IRQs are enabled.
If ``state`` is ``False`` then IRQs are disabled. The most common use of
this function is to pass it the value returned by ``disable_irq`` to
exit a critical section.

``machine.DEEPSLEEP``. Wake sources are ``Pin`` and ``RTC``. Current consumption

.. function:: wake_reason()

Miscellaneous functions
-----------------------
.. function:: main(filename)
.. only:: port_wipy
Set the filename of the main script to run after boot.py is finished. If
this function is not called then the default file main.py will be executed.
.. function:: main(filename)
It only makes sense to call this function from within boot.py.
Set the filename of the main script to run after boot.py is finished. If
this function is not called then the default file main.py will be executed.
.. function:: rng()
It only makes sense to call this function from within boot.py.
Return a 24-bit software generated random number.
.. function:: rng()
Return a 24-bit software generated random number.
.. function:: unique_id()
Returns a string of 6 bytes (48 bits), which is the unique ID of the MCU.
This also corresponds to the network ``MAC address``.
Returns a byte string with a unique idenifier of a board/SoC. It will vary
from a board/SoC instance to another, if underlying hardware allows. Length
varies by hardware (so use substring of a full value if you expect a short
ID). In some MicroPython ports, ID corresponds to the network MAC address.
