DC CHARACTERISTICS (TA = –40 to +85

°C, VDD = 3.5 to 5.5 V)

Note

When an input instruction is executed, the low-level input leakage current for P60 to P63 becomes –200

µA (MAX.) only in one clock cycle (at no wait). It remains at –3 µA (MAX.) for other than an input instruction.

Remark The characteristics of alternate-function pins and port pins are the same unless specified otherwise.
