Schmitt trigger

Pull-up

General purpose IO pin.

During reset, the pull-up resistor is connected (input

disable state). The pull-up and pull-down resistors

are unconnected (input disable state) just after the

reset is released, and it will be controlled by

software after that.

After the pin configuration by software processing, it

works as a GPIO pin of the input and output or

Table 2-2 function. (Note)

Hi-Z

General purpose I/O pin.

During reset, the pull-up and pull-down resistors are

unconnected (input disable state). The pull-up

resistor is connected (input state) just after the reset

is released, and it will be controlled by software after

that. After the pin configuration by software

processing, it works as a GPIO pin of the input and

output or Table 2-2 function.

Pin processing when not using this function are

listed in Table 2-2. (Note))

Schmitt trigger

Pull-down

Serial Wire debugger clock pin.

During reset, the pull-down resistor is connected

(input state). After the reset is released, the serial

wire debugger clock is inputted.

When not used, this pin should be open.

Pull-up

Serial Wire Debugger data pin and operation

switching pin.

During reset, the pull-up resistor is connected (input

state). After the reset is released, the serial wire

debugger data is inputted and outputted.

When not used, this pin should be open.

Schmitt trigger

—

Test mode setting pin.

This pin is used for IC manufacturing test and

needs to be connected to GND when assembled

on a board.

VDD12A

IN/OUT

Analog

—

Analog test pins.

These pins are used for IC manufacturing test and

need to be connected to GND when assembled on

a board.

Note: The state of the GPIO pin corresponds to the usage state in the user application mode. Since states differ partially when the

operation is powered on with the HCI mode, please refer to the software application note about the detailed state and its setting

method of each pin.
