Pin interrupts are supported through ``attachInterrupt``, Pin interrupts are supported through ``attachInterrupt``,
``detachInterrupt`` functions. Interrupts may be attached to any GPIO ``detachInterrupt`` functions. Interrupts may be attached to any GPIO
pin, except GPIO16. Standard Arduino interrupt types are supported: pin, except GPIO16. Standard Arduino interrupt types are supported:
``CHANGE``, ``RISING``, ``FALLING``. ``CHANGE``, ``RISING``, ``FALLING``. ISRs need to have
``ICACHE_RAM_ATTR`` before the function definition.
