• “NC” means: leave unconnected.
• GND
means internally connected to Ground plane of
module (51 pins in total)
• GND means connect to Ground (not supported,
functional pin)
Reset States:
• I = Input
• O= Output
• I-PD = Input, pulled down
• I-PU = Input, pulled up
• O-0 = Output, low
• O-1 = Output, high
