The xmega code mods make a considerable number of assumptions
about the pin number assignments (as defined here):
DEFAULT MAPPING ('DIGITAL_IO_PIN_SHIFT' NOT DEFINED)
----------------------------------------------------
PORTD - digital 0-7
PORTC - digital 8-15
PORTE - digital 16-20
PORTR - digital 20-21 (built-in LED on PORTR pin 1, aka '21')
PORTA - analog 0-7, digital 22-29
PORTB - analog 8-11, digital 30-33
SPI is assumed to be on PORTC (pins 4-7)
Serial is implemented on PORTD, Serial2 on PORTC, both using pins 2,3 (no flow control)
PORTR pin 1 is assumed to be connected to an LED. Pin 1 is the 'built-in' LED, defined
as 'LED_BUILTIN', and is active HIGH.
Your Mileage May Vary, depending on your board layout. Some boards shift the
digital pin assignments by 2 so that digital I/O pin 0 is PORTD Rx, pin 13 is PORTC SCK, just
like the Arduino ATmega board. Then they align the physical pins so that a regular Arduino shield
will work, and assign PORTD 0-1 to 2 different digital I/O pin numbers (such as 20 and 21).
To facilitate that specific change, uncomment the #define for 'DIGITAL_IO_PIN_SHIFT', below.
Alternately you can create a separate version of this file with a different variant name,
such as 'xmega-compat', with the #define uncommented, stored in an appropriately named directory.
============================
HARDWARE SERIAL FLOW CONTROL
============================
This version of the xmega Arduino startup+support files supports HARDWARE FLOW CONTROL on BOTH serial ports via
RTS (output) and CTS (input). CTS is implemented as input from remote device's DTR. RTS is implemented as DTR output.
To implement RTS/CTS, use definitions similar to the following in your version of this header file
NOTE: RTS(DTR) will be configured as an output, active low (high tells sender to stop sending data to the UART)
CTS will be configured as an input, active low (high stops data from being sent out via UART)
CTS high to low transition causes an interrupt that may result in serial I/O (for faster response time).
// RTS(DTR) as GPIO 0 (port D pin 0)
#define SERIAL_0_RTS_PORT_NAME PORTD
#define SERIAL_0_RTS_PIN_INDEX 0
// CTS as GPIO 1 (port D pin 1)
#define SERIAL_0_CTS_PORT_NAME PORTD
#define SERIAL_0_CTS_PIN_INDEX 1
use similar definitions for serial 1, aka 'SERIAL_1_CTS_PORT'
NOTE: you can even use PORTA or PORTB pins for this, if you don't need to measure analog volts on those pins

//
// ALL PORT REMAP registers must be assigned to 0 (default mappings for pins)

// Timer 0 should be configured as 'Tx2' (for 8 PWM outputs) by default, essentially
// as a dual 8-bit timer, more or less compatible with the Arduino's 3 timers and
// supporting all 8 pins on ports C and D for PWM output. Port C's timer supports
