Name
P0.7:0
Type
I/O
Description
Port 0
P0 is an 8-bit open-drain bidirectional I/O port. Port 0 pins that have 1s written
to them float and can be used as high impedance inputs. To avoid any parasitic
current consumption, floating P0 inputs must be polarized to VDD or VSS.
P1.7:0
I/O
Port 1
P1 is an 8-bit bidirectional I/O port with internal pull-ups.
