Input:

Input gate in operation. Fix input voltage to 0 or 1 so that the input pin stays constant.

Output: Output state

Invalid: Input is not accepted.

High-Z: Output is at high impedance.

PU:

Programmable pull-up pin in input gate in operation. Fix the pin to avoid through current since the input gate

operates when a pull-up pin resistance is not set.

PU*:

Programmable pull-up pin in input gate disable state. No through current even if the pin is set to high

impedance.

∆:

When a HALT instruction is executed and the CPU stops at the address of the port register, an input gate

operates. Fix the pin to avoid through current, and change the program.

In all other cases, input is not accepted.

Note:

Port registers are used for controlling programmable pull up. If a pin is also used for an output function (e.g.

TO3) and the output function is specified, whether pull up is selected depends on the output function data.

If a pin is also used for an input function, whether pull up is selected depends on the port register setting

value only.
