- /**
- * Due/Marlin quirks
- *
- * a) determining the state of a pin
- * The Due/Arduino status definitions for the g_pinStatus[pin] array are:
- * #define PIN_STATUS_DIGITAL_INPUT_PULLUP (0x01)
- * #define PIN_STATUS_DIGITAL_INPUT (0x02)
- * #define PIN_STATUS_DIGITAL_OUTPUT (0x03)
- * #define PIN_STATUS_ANALOG (0x04)
- * #define PIN_STATUS_PWM (0x05)
- * #define PIN_STATUS_TIMER (0x06)
- *
- * These are only valid if the following Due/Arduino provided functions are used:
- * analogRead
- * analogWrite
- * digitalWrite
- * pinMode
- *
- * The FASTIO routines do not touch the g_pinStatus[pin] array.
- *
- * The net result is that both the g_pinStatus[pin] array and the PIO_OSR register
- * needs to be looked at when determining if a pin is an input or an output.
- *
- * b) Due has only pins 6, 7, 8 & 9 enabled for PWMs. FYI - they run at 1KHz
- *
- * c) NUM_DIGITAL_PINS does not include the analog pins
- *
- * d) Pins 0-78 are defined for Due but 78 has a comment of "unconnected!". 78 is
- * included just in case.
