5.12 Output Frequency (Ports Px)over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
||Port output frequency (with load)
||Px.y, CL = 20 pF, RL = 1 kΩ(1)(2)
||Clock output frequency
||Px.y, CL = 20 pF(2)
(1) A resistive divider with two 0.5-kΩ resistors between VCC and VSS is used as load. The output is connected to the center tap of the divider.
(2) The output voltage reaches at least 10% and 90% VCC at the specified toggle frequency.
