3: The total average input current for ports P3
4: Connect 0.1 F or more capacitor externally between the power source pins V
5: Use a quartz-crystal oscillator or a ceramic resonator for the CPU oscillation circuit. When using the data slicer, use 8 MHz.
6: P1
7: When using the sub-clock, set f
8: Pin names in each parameter is described as below.
