Pin
Names
Type
I/O
I/O port with bit-programmable pins. Configurable
P0.0–P0.7
to input or push-pull output mode. Pull-up resistors
are assignable by software. Pins can be assigned
individually as external interrupt inputs with noise
filters, interrupt enable/ disable, and interrupt
pending control. SED&R (note) circuit built in P0
for STOP releasing.
I/O
I/O port with bit-programmable pins. Configurable
P1.0–P1.7
to input mode or output mode. Pin circuits are
either push-pull or n-channel open-drain type.
I/O
I/O port with bit-programmable pins. Configurable
P2.0–P2.3
to input or push-pull output mode. Pull-up resistors
P2.4–P2.7
can be assigned by software. Pins can be
assigned individually as external interrupt inputs
with noise filters, interrupt enable/disable, and
interrupt pending control. SED & R (note) circuit
built in P2-P2.7 for STOP releasing. Also P2.4-
P2.7 can be assigned individually as analog input
pins for Comparator.
I/O
I/O port with bit-programmable pin. Configurable to
P3.0
input mode, push-pull output mode, or n-channel
open-drain output mode. Input mode with a pull-up
resistor can be assigned by software.
This port 3 pin has high current drive capability.
Also P3.0 can be assigned individually as an
output pin for T0PWM or input pin for T0CAP.
In the tool mode, P3.0 is assigned as serial MTP
interface pin; SDAT
I/O
I/O port with bit-programmable pin. Configurable to
P3.1
input mode, push-pull output mode, or n-channel
open-drain output mode. Input mode with a pull-up
resistor can be assigned by software.
This port 3 pin has high current drive capability.
Also P3.1 can be assigned individually as an
output pin for REM.
In the tool mode, P3.1 is assigned as serial MTP
interface pin; SCLK
