Notes 1.
Circuit types enclosed in brackets 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, connection of on-chip pull-
up resistors can be specified by software in
3-bit units.
4-bit input port (PORT1).
Connection of on-chip pull-up resistors can
be specified by software in 4-bit units.
Only P10/INT0 can select noise elimination
circuit.
4-bit input/output port (PORT2).
Connection of on-chip pull-up resistors can
be specified by software in 4-bit units.
Programmable 4-bit input/output port
(PORT3).
This port can be specified for input/output
bit-wise.
Connection of on-chip pull-up resistor can
be specified by 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.
