Port0 is an open-drain, bi-directional IO
port. When 1s are written to Port0, they
become high-impedance inputs. Port0 is
also multiplexed with low-order address
or data bus during accesses to external
program and data memory.

BU
General-purposed I/O with weak pull-up
resistance inside. When 1s are written
into Port1, the strong output driving
PMOS only turn-on two clock periods
and then the weak pull-up resistance
keep the port high.
P1.0 is also used as one of event
sources for timer2, or output carrier of
timer2, alias T2.
P1.1
is
also
used
as
one
of
interrupt-controlling sources for time2,
alias T2EX.

Port2 is an 8-bit bi-directional I/O port
with pull-up resistance. Except being as
GPIO,
Port2
emits
the
high-order
address
byte
during
accessing
to
external program and data memory.
