/* The standard PinDescription table uses 12 bytes per pin. Define PIN_DESCRIPTION_TABLE_SIMPLE
* to use a more compact format that uses only 4 bytes per pin (currently only available
* for the D11 chips). In this case, the PinType, PinAttribute, and GCLKCCL columns are not used
* (they are not required). Additionally, the SetPortPin() and SetExtIntADC() macros are used to
* pack Port and Pin into the PortPin column, and ExtInt and ADCChannelNumber into the ExtIntADC
* column. See the variant README.md for more information. Note that external libraries that
* reference the PinDescription table directly (uncommon) will no longer work. This define can be
* combined with the PIN_MAP_COMPACT define, which is available in variant.h of the D11 variants.
* This can save from 10's to over 250 bytes.

* Note that when using this define, EXTERNAL_INT_15 and the EXTERNAL_INT_NMI are NOT available
* and only ADC_Channel0 through ADC_Channel14 are available.

* expects the associated hardware to be already initialized. Note that if using a core function
