1.4.3 Oscillator protection using Vss pattern
• As for an input port, read data several times by a program for checking whether input levels are equal or
• As for an output port, since the output data may reverse because of noise, rewrite data to its port latch
• Rewrite data to direction registers and pull-up control registers at fixed periods.
• Connect a resistor of 100
