‡ _{For I/O ports, the parameters IOZH and IOZL include the input leakage current.}
§ _{The bus-hold circuit can sink at least the minimum low sustaining current at VIL max. IBHL should be measured after lowering VIN to GND, then raising}
it to VIL max.
¶ _{The bus-hold circuit can source at least the minimum high sustaining current at VIH min. IBHH should be measured after raising VIN to VCC, then lowering}
it to VIH min.
# _{An external driver must source at least IBHLO to switch this node from low to high.}
|| _{An external driver must sink at least IBHHO to switch this node from high to low.}
k _{High-impedance state during power up or power down}
