Port 4
is a 8-bit quasi-bidirectional port with internal pull-up
arrangement. Port 4 pins that have a 1 written to them are
pulled high by the internal pull-up transistors and in that
state can be used as inputs. As inputs, port 4 pins being
externally pulled low will source current (
I
IL
, in the DC
characteristics) because of the internal pullup transistors.
Port 4 pins can also be configured as LCD column outputs.
The secondary functions are assigned to the pins of port 4
as follows:
P4.0 / C16
LCD column output 16
P4.1 / C17
LCD column output 17
P4.2 / C18
LCD column output 18
P4.3 / C19
LCD column output 19
P4.4 / C20
LCD column output 20
P4.5 / C21
LCD column output 21
P4.6 / C22
LCD column output 22
P4.7 / C23
LCD column output 23
These pins should not be used for input when configured as
LCD output pins.

Port 5
is a 6-bit quasi-bidirectional port with internal pull-up
arrangement. Port 5 pins that have a 1 written to them are
pulled high by internal pull-up transistors and in that state
can be used as inputs. As inputs, port 5 pins being
externally pulled low will source current (
I
IL
, in the DC
characteristics) because of the internal pullup transistors.
Port 5 pins can also be configured as LCD column outputs.
The secondary functions are assigned to the pins of port 5
as follows:
P5.0 / C24
LCD column output 24
P5.1 / C25
LCD column output 25
P5.2 / C26
LCD column output 26
P5.3 / C27
LCD column output 27
P5.4 / C28
LCD column output 28
P5.5 / C29
LCD column output 29
These pins should not be used for input when configured as
LCD output pins.
