NOTES:
71
Pins marked with a ~ (tilda) means that the board advertises it has PWM.
72
Pins marked with ~' (tilda followed by an apostrophe) means that we do PWM on a different timer than the board normally uses.
73
Pins marked with ?~ (question mark followed by tilda) means that PWM is not advertised but the pin attributes in variant.cpp indicate it is available
74
Pins marked with ni means "no interrupt". The attachInterrupt() method is not supported and cannot be used for IRrecvPCI or IRfreq receivers.
75
The primary use of the pin is listed first and alternate uses are separated by commas.
