P0.7:0

I/O

Port 0

P0 is an 8-bit open-drain bi-directional 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.

AD7:0

P1.7:0

I/O

Port 1

P1 is an 8-bit bi-directional I/O port with internal pull-ups.
