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, connections of on-chip
pull-up resistors can be specified by
software in 3-bit units.
4-bit input port (PORT1)
Connections of on-chip pull-up resistors
can be specified by software in 4-bit units.
P10/INT0 can select noise eliminating
circuit.
4-bit input/output port (PORT2)
Connections 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 input/output in bit
units. Connections 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).
In the open-drain mode, withstands up to 13 V.
N-ch open-drain 4-bit input/output port
(PORT5).
A pull-up resistor can be contained bit-wise
(mask option).
In the open-drain mode, withstands up to 13 V.
