NOTES:
1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for port 0, ALE, and PSEN = 100pF, load capacitance for all other outputs = 80pF.
3. These values are characterized but not 100% production tested.
4. tCLCL = 1/fOSC = one oscillator clock period.
tCLCL = 41.7ns at fOSC = 24MHz.
