I/O 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.

I/O Port 1 is an 8-bit bidirectional I/O port

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.

P1.5

P1.6

P1.7

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 timer2,

alias T2EX.

I/O Port 2 is an 8-bit bidirectional I/O port

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 address bytes during

accessing to external program and

data memory.
