Notes 1: The total current that flows out of the IC must be 20 or less.
2: The total input current to IC (IOL1 + IOL2 + IOL3) must be 20 mA or less.
3: The total average input current for ports P30, P31 to IC must be 10 mA or less.
4: Connect 0.1 µF or more capacitor externally between the power source pins VCC–VSS (and AVCC–VSS ) so as to reduce power source noise.
Also connect 0.1 µF or more capacitor externally between the pins VCC–CNVSS. ( ) ^{...M37280EKSP}
5: Use a quartz-crystal oscillator or a ceramic resonator for the CPU oscillation circuit. When using the data slicer, use 8 MHz.
6: P16, P41–P44 have the hysteresis when these pins are used as interrupt input pins or timer input pins. P11–P14 have the hysteresis when these pins are
used as multi-master I²C-BUS interface ports. P17, P46 and P72 have the hysteresis when these pins are used as serial I/O pins.
7: When using the sub-clock, set fCLK < fCPU/3.
8: Pin names in each parameter is described as below.
(1) Dedicated pins: dedicated pin names.
(2) Duble-/triple-function ports
• When the same limits: I/O port name.
• When the limits of functins except ports are different from I/O port limits: function pin name.
