* calculated by taking the second letter of the pin number, converting to its alphabetic number equivalent, subtracting one, multiplying by 32, and then adding the numerical part of the pin number. e.g. PC13 = (C-1)*32+13 = (3-1)*32+13 = 77. See this thread.

P=”Pin”
C=3rd bank of GPIO connections.
13=GPIO in that specific bank.
