Note: Ports PB through PG, and PJ through PT are all left open.
However, ports PB through PG, PK through PT, EO3, and
SUBPD are left open in output mode.
Note: Ports PA through PT are all left open.

Function
Equivalent circuit
Dedicated input ports.
These ports are designed with a low threshold voltage.
The pull-down resistors for all four pins are set up together with an IOS1 instruction.
The pull-down resistors cannot be set individually.
Input is disabled in backup mode.

I
General-purpose I/O ports
The mode (input or output) is set using the IOS2 instruction.
Input is disabled and the pins go to the high-impedance state in backup mode.
These ports are set up as general-purpose input ports after a power on reset.

I/O
General-purpose I/O ports (high-voltage input and output)
The mode (input or output) is set using the IOS2 instruction.
External pull-up resistors are required since the output circuits are open drain
circuits.
Input is disabled and the pins go to the high-impedance state in backup mode.
These ports are set up as general-purpose input ports after a power on reset.

I/O
General-purpose I/O and external interrupt shared function ports
The input formats are Schmitt inputs.
The external interrupt function is enabled when the external interrupt enable flag is
set.
When used as general-purpose I/O ports:
The mode (input or output) is set in 1-bit units using the IOS2 instruction.
When used as external interrupt pins:
The external interrupt functions are enabled by setting the corresponding external
interrupt enable flag (INT4EN or INT5EN). Here, the pins must be set to input
mode in advance.
Input is disabled and the pins go to the high-impedance state in backup mode.
These ports are set up as general-purpose input ports after a power on reset.
