No Connect. Leave these pins unconnected.
Legend: I = Input only;
O = Output only;
I/O = Input/Output;
P = Power;
— = Not Used;
TTL = TTL input; ST = Schmitt Trigger input.
Note 1: The output is only available by the peripheral operation.
2: Open Drain input/output pin. Pin forced to input upon any device reset.
