• After the replacement, pins 44 to 47 can be used as general purpose I/O output function. (pin 48 open)
• It is necessary to review the circuit pattern of the printed circuit board because the I/O setting of pin 48 differs from
each other.

• It is necessary to review the circuit pattern of the printed circuit board to change the pull-up resistor of pin 35 to the
pull-down resistor because pins 44 to 47 is used as general purpose I/O input function.
• It is necessary to review the circuit pattern of the printed circuit board because the I/O setting of pin 48 differs from
each other.
