/**
* Endstop interrupts
* Without endstop interrups the stepper-ISR must always test all endstops when interested in their states (endstops.update()).
* Most time the test will result in finding out nothing has changed.
* With endstop interrupts endstops.update() is called only when we know that at least one endstop has changed its state.
* Endstop Interrupts
*
* This can work only if all __used__ endstop pins can provide ether an 'external interrupt' or a 'pin change interrupt'.
* You can find out about pins issuing interrupts by running 'pin_interrupt_test.ino' (Marlin\buildroot\share\pin_interrupt_test\pin_interrupt_test.ino)
* Without endstop interrupts the endstop pins must be polled continually in
* the stepper-ISR via endstops.update(), most of the time finding no change.
* With this feature endstops.update() is called only when we know that at
* least one endstop has changed state, saving valuable CPU cycles.
*
* This feature only works when all used endstop pins can generate either an
* 'external interrupt' or a 'pin change interrupt'.
*
* Test whether pins issue interrupts on your board by flashing 'pin_interrupt_test.ino'.
* (Located in Marlin/buildroot/share/pin_interrupt_test/pin_interrupt_test.ino)
