Type
I/O Port0 is an open-drain, bi-directional
I/O Port 1 is an 8-bit bidirectional I/O port
I/O Port 2 is an 8-bit bidirectional I/O port
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.
with internal pull-ups and can be used
as inputs. Port 1 pins that have 1s
written to them are pulled high by the
internal pull-ups and can be used as
inputs. As inputs, port 1 pins that are
externally pulled low will source current
because of the internal pull-ups.
P1.0 is also used as one of event
sources for timer2, or output carrier of
timer2, alias T2.
P1.1
interrupt-controlling sources for timer2,
alias T2EX.
with internal pull-ups and can be used
as inputs. Port 2 pins that have 1s
written to them are pulled high by the
internal pull-ups and can be used as
inputs. As inputs, port 2 pins that are
externally pulled low will source current
because of the internal pull-ups.
Except being as GPIO, Port2 emits the
high-order
accessing to external program and
data memory.
