TECHNICAL DATA
NOTES:
1. VOH specification for RESET and MODA is not applicable because they are open-drain pins. VOH specification
not applicable to ports C and D in wired-OR mode.
2. EXTAL is driven with a square wave, and
tcyc = 1000 ns for 1 MHz rating;
tcyc = 500 ns for 2 MHz rating;
tcyc = 333 ns for 3 MHz rating;
VIL ≤ 0.2 V;VIH ≥ VDD - 0.2 V;
No dc loads.
