Port 0 is an 8-bit open drain
bidirectional I/O port. Port 0 pins
that have 1s written to them float; in
this state they can be used as high-
impedance inputs (e.g. for software
driven
I
C Bus).

Port 1 is an 8-bit bidirectional
multifunctional I/O port with internal
pullup resistors. Port 1 pins that
have 1s written to them are pulled
high by the internal pullup resistors
and in that state can be used as
inputs.
The secondary functions of port 1
pins are:
Port bits P1.0 - P1.5 contain the
6 output channels of the 8-bit pulse
width modulation unit.
Port bits P1.6 - P1.7 contain the two
output channels of the 14-bit pulse
width modulation unit.
