Notes 1.
Circled characters indicate the Schmitt-trigger input.
If on-chip pull-up resistors are not specified by mask option (when used as N-ch open-drain input port),
low level input leakage current increases when input or bit manipulation instruction is executed.
2.
4-bit input port (PORT0).
For P01 to P03, on-chip pull-up resistors
can be specified in software in 3-bit units.
4-bit input port (PORT1).
On-chip pull-up resistors can be specified
in software in 4-bit units.
Noise eliminator can be selected (Only
P10/INT0)
4-bit input/output port (PORT2).
On-chip pull-up resistors can be specified
in software in 4-bit units.
Programmable 4-bit input/output port
(PORT3).
This port can be specified input/output in
bit units.
On-chip pull-up resistor can be specified in
software in 4-bit units.
N-ch open-drain 4-bit input/output port
(PORT4).
A pull-up resistor can be contained bit-wise
(mask option).
Withstand voltage is 13 V in open-drain mode.
N-ch open-drain 4-bit input/output port
(PORT5).
A pull-up resistor can be contained bit-wise
(mask option).
Withstand voltage is 13 V in open-drain mode.
