8. MCU Pin Setting Examples

Table 10 shows examples of settings for each MCU pin. Refer to instructions in the corresponding MCU user’s manual:
hardware on how to treat unused pins for functions not used on the evaluation board.

[Notice]

The MCU pull-up resistor is set in 4-bit units for most of the pins. When using the MCU internal pull-up

resistor to process unused pins, be sure that the resistor setting does not affect the function of other pins

set at the same time.
