Input:

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

Output:

Output state.

Output*: Open-drain output state. Input gate in operation. Set output to “L” or attach pull up on pin so that the input gate stays

constant.

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 resistor 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.

×:

Cannot set.

■:

To connect a low-frequency resonator to port 66 and port 67, it is necessary to set the following procedures to reduce

the consumption power supply.

(Connecting to a resonater)

Set P6CR<P66C:67C>

= “11”, P6<P66:67> = “00”

(Connecting to an oscillator)

Set P6CR<P66C:67C>

= “11”, P6<P66:67> = “10”

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.
