Cautions: 1. Refer to the section entitled "Flowcharts" in RL78/G13 Initialization Application Note (R01AN2575E)

2. Provide proper treatment for unused pins so that their electrical specifications are met. Connect each of
any unused input-only ports to V
DD

SS
via a separate resistor.
3. Set the I/O port to a high level because the LED connected to P63 is always off.
