/* enableInterrupt- Sets up an interrupt on a selected Arduino pin.
* or
* enableInterruptFast- When used with the NEEDFORSPEED macro, sets up an interrupt on a selected Arduino pin.
*
* Usage:
* enableInterrupt(uint8_t pinNumber, void (*userFunction)(void), uint8_t mode);
* or
* enableInterrupt(uint8_t interruptDesignator, void (*userFunction)(void), uint8_t mode);
*
* For HiSpeed mode,
* enableInterruptFast(uint8_t pinNumber, uint8_t mode);
* or
* enableInterruptFast(uint8_t interruptDesignator, uint8_t mode);
*
* ---------------------------------------------------------------------------------------
*
* disableInterrupt- Disables interrupt on a selected Arduino pin.
*
* Usage:
*
* disableInterrupt(uint8_t pinNumber);
* or
* disableInterrupt(uint8_t interruptDesignator);
*
* ---------------------------------------------------------------------------------------
*
* interruptDesignator: Essentially this is an Arduino pin, and if that's all you want to give
* the function, it will work just fine. Why is it called an "interruptDesignator", then? Because
* there's a twist: You can perform a bitwise "and" with the pin number and PINCHANGEINTERRUPT
* to specify that you want to use a Pin Change Interrupt type of interrupt on those pins that
* support both Pin Change and External Interrupts. Otherwise, the library will choose whatever
* interrupt type (External, or Pin Change) normally applies to that pin, with priority to
* External Interrupt.
*
* The interruptDesignator is required because on the ATmega328 processor pins 2 and 3 support
* ''either'' pin change or * external interrupts. On 644/1284-based systems, pin change interrupts
* are supported on all pins and external interrupts are supported on pins 2, 10, and 11.
* Otherwise, each pin only supports a single type of interrupt and the
* PINCHANGEINTERRUPT scheme changes nothing. This means you can ignore this whole discussion
* for ATmega2560- or ATmega32U4-based Arduinos. You can probably safely ignore it for
* ATmega328-based Arduinos, too.
