/**
 * G2 uses 8 pins that are not available in the DUE environment:
 *   34 PA29 - Y_STEP_PIN
 *   35 PB1  - Y_DIR_PIN
 *   36 PB0  - Y_ENABLE_PIN
 *   37 PB22 - E0_ENABLE_PIN
 *   38 PB11 - E0_MS1_PIN - normally used by the USB native port
 *   39 PB10 - E0_MS3_PIN - normally used by the USB native port
 *   40 PA5  - HEATER_0_PIN
 *   41 PB24 - HEATER_BED_PIN
 *
 * None of these are in the arduino_due_x variant so digitalWrite and digitalRead can't be used on them.
 *
 * They can be accessed via FASTIO functions WRITE, READ, OUT_WRITE, OUTPUT, ...
