Function
Port 3
8-bit I/O port
Can be specified for input or output in 1-bit units.
Can directly drive LEDs.
When used as an input port pin, an on-chip pull-up resistor can be used through software.
A pull-down resistor can be connected in 1-bit units by mask option.
Port 2
8-bit I/O port
Can be specified for input or output in 1-bit units.
When used as an input port pin, an on-chip pull-up resistor can be used through software.
Port 1
8-bit I/O port
Can be specified for input or output in 1-bit units.
When used as an input port pin, an on-chip pull-up resistor can be used through software.
(Note 2)
Port 0
5-bit I/O port
Can be specified for input or output in 1-bit units.
When used as an input port pin, an on-chip pull-up resistor can be
used through software.
Port 7
5-bit N-ch open-drain I/O port
Can be specified for input or output in 1-bit units.
Can directly drive LEDs.
A pull-up resistor can be connected in 1-bit units by mask options.
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
Notes: 1. When the P04/XT1 pins is used as an input port pin, bit 6 (FRC) of the processor clock control register (PCC) must be
set to 1. (At this time, do not use the feedback resistor of the subsystem clock oscillator circuit.)
2. When the P10/ANI0 through P17/ANI7 pins are used as the analog input lines of the A/D converter, be sure to place
the port 1 in the input mode. In this case, the pull-up resistors are automaticaly unused.
