(1) The maximum total current, I_(OHmax) and I_(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop
specified.
(2) The maximum total current, I_(OHmax) and I_(OLmax), for all outputs combined should not exceed ±100 mA to hold the maximum voltage
drop specified.
(3) The port can output frequencies at least up to the specified limit - it might support higher frequencies.
(4) A resistive divider with 2 × R1 and R1 = 3.2kΩ between V_CC and V_SS is used as load. The output is connected to the center tap of the
divider. C_L = 20pF is connected to the output to V_SS.
(5) The output voltage reaches at least 20% and 80% V_CC at the specified toggle frequency.
(6) Measured between 20% of V_CC to 80% of V_CC.
(7) Measured between 80% of V_CC to 20% of V_CC.
