I/O
General-purpose I/O ports
The mode is switched between input and output with the IOS
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 port and beep tone output shared function ports.
The IOS2 instruction is used to switch between the general-purpose
I/O port and the beep tone output functions.
When used as general-purpose I/O ports :
The general-purpose I/O port function is set up with the IOS2
instruction.
(Pins PN1 through PN3 are dedicated general-purpose output pins.)
When used as the beep tone output pin :
The beep tone output function is set up with the IOS2 instruction.
The frequency is set up with the BEEP instruction.
When this pin is used as the beep tone output pin, executing an
output instruction for this pin only sets the internal latch and has no
influence on the output.
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
The mode is switched between input and output with the IOS
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.
The mode is switched between input and output with the IOS
instruction, and data is input with the INR instruction and output with
the OUTR instruction.
The SPB, RPB, TPT, and TPF instruction cannot be used with these
ports.
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.
