This sample uses an interrupt service routine (ISR) named `blink` to toggle
a global state variable and then uses the built-in LED to display the value
of the cached state to the user. The work of updating the cached state happens
asychronously in the interrupt service routine.
asynchronously in the interrupt service routine.

a switch, by changing the interrupt mode from CHANGE to LOW. Furthermore, this
