/**
* A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
* The servos are pulsed in the background using the value most recently written using the write() method
*
* Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
* Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
*
* The methods are:
*
* Servo - Class for manipulating servo motors connected to Arduino pins.
*
* attach(pin) - Attach a servo motor to an i/o pin.
* attach(pin, min, max) - Attach to a pin, setting min and max values in microseconds
* Default min is 544, max is 2400
*
* write() - Set the servo angle in degrees. (Invalid angles —over MIN_PULSE_WIDTH— are treated as µs.)
* writeMicroseconds() - Set the servo pulse width in microseconds.
* move(pin, angle) - Sequence of attach(pin), write(angle), safe_delay(servo_delay[servoIndex]).
* With DEACTIVATE_SERVOS_AFTER_MOVE it detaches after servo_delay[servoIndex].
* read() - Get the last-written servo pulse width as an angle between 0 and 180.
* readMicroseconds() - Get the last-written servo pulse width in microseconds.
* attached() - Return true if a servo is attached.
* detach() - Stop an attached servo from pulsing its i/o pin.

/**
* Endstop Interrupts
*
* Without endstop interrupts the endstop pins must be polled continually in
* the temperature-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)

* Patch for pins_arduino.h (...\Arduino\hardware\arduino\avr\variants\mega\pins_arduino.h)

* These macros for the Arduino MEGA do not include the two connected pins on Port J (D14, D15).
* So we extend them here because these are the normal pins for Y_MIN and Y_MAX on RAMPS.
* There are more PCI-enabled processor pins on Port J, but they are not connected to Arduino MEGA.
