4-bit input/output port Input/output is specifiable
bit-wise. When used as the
input port, it is possible to
connect a pull-up resistor by
software.
Port 1
8-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to connect
a pull-up resistor by software. ^Note
Port 3
8-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to connect
a pull-up resistor by software.
Port 5
8-bit input/output port
Can drive up to seven LEDs directly.
Input/output is specifiable bit-wise.
When used as the input port, it is possible to connect
a pull-up resistor by software.
Port 7
3-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to connect
a pull-up resistor by software.
Port 10
2-bit input/output port
Input/output is specifiable bit-wise.
