(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) _{tCLK = 1/fosc = one oscillator clock period.}
(5) _{tMCS is a time period related to the Stretch MOVX selection. The following table shows the value of tMCS for each stretch selection:}
