/**
* 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.
