Power supply pins capacitor must inserted between power supply pins noise exclusion. This capacitor must located close possible these pins. FMIN AMIN pins coupling capacitors must located close possible these pins. pins, low-pass filter Since those high-impedance pins, they susceptible noise. Therefore, pattern should kept short possible area around this circuit should covered ground pattern. Initial states output ports (BO1 BO3) initial states output ports after power applied undefined until data been transferred. particular, possible pins output internal clock, data must transferred soon possible. However, note that cannot accept data until crystal oscillator operating normally.
