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.
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.
