Chapter 1 Overview
Unused pins (for I/O)
Unused I/O pins should be set according to pins' condition at reset. If the output is high impedance (Pch
/ Nch transistor : output off) at reset, to stabilize input, set 10 k to 100 k resistor to be pull-up or pull-
down. If the output is on at reset, set them open.
