Rev.1.923
In order to reduce pin count, and therefore size and cost, some pins have multiple functions. In those cases, the functions are
separated with a “/” symbol. Refer to the Pin Assignment diagram for a graphical representation.
'I' stands for input
'O' stands for output
'A' stands for analog signal
'D' stands for digital signal
'P' stands for power
'G' stands for ground
'Pu' stand for internal pull up (75K ohm)
'Pd' stand for internal pull down (75K ohm)
