Input
4-bit input port (P0):
These are 4-bit input ports permitting selection of the pull-up
resistance input/pull-down resistance input/high impedance
input through the control register of port 01 (P01CON).
As the secondary functions, an external interrupt function is
allocated to P0.0 to P0.3 and a capture trigger function is
assigned to P0.0 and P0.1.

Output 4-bit output port (P1):
These are 4-bit output ports permitting selection of the NMOS
open drain output/CMOS output through the control register of
port 01 (P01CON).
P1.0 is a large electric current driving output port.
P1.1

Input/
Output
4-bit input/output port (P2):
These are 4-bit input/output ports permitting selection of
input/output per bit through the control registers 0 to 3 of port 2
(P20CON to P23CON), selection of the pull-up and pull-down
rsistance input/high impedance input, and selection of the
NMOS open drain output/CMOS output. As the secondary
functions, an external interrupt function is allocated.

Output
4-bit input/output port (P4):
These are 4-bit input/output ports permitting selection of the
input/output per bit through the control registers 0 to 3 of port 4
(P40CON to P43CON), selection of the pull-up and pull-down
resistance input/high impedance input, and selection of the
NMOS open drain output/CMOS output. As the secondary
functions, P4.0 to P4.3 have an external interrupt function, P4.0
to P4.2 have a serial port function, and P4.3 has a monitor
function of a CR oscillation clock for AD conversion.
