Type: I = input, O = output, S = supply
Input level: C
Output level: HS = 20mA high sink (on N-buffer only)
Port and control configuration inputs: float = floating, wpu = weak pull-up, int = interrupt, ana = analog ports
Port and control configuration outputs: OD = open drain, PP = push-pull
(int), then the I/O configuration is pull-up interrupt input; otherwise the configuration is floating interrupt input
