Notes to Table 1–12:
(1) All I/O pins have an option to enable weak pull-up except the configuration, test, and JTAG pins. The weak pull-down feature is only available
for JTAG TCK.
(2) Pin pull-up resistance values may be lower if an external source drives the pin higher than V_CCIO.
(3) R_{_PU} = (V_CCIO – V_I)/I_{R_PU}
Minimum condition: –40°C; V_CCIO = V_CC + 5%, V_I = V_CC + 5% – 50 mV;
Typical condition: 25°C; V_CCIO = V_CC, V_I = 0 V;
Maximum condition: 100°C; V_CCIO = V_CC – 5%, V_I = 0 V; in which V_I refers to the input voltage at the I/O pin.
(4) R_{_PD} = V_I/I_{R_PD}
Minimum condition: –40°C; V_CCIO = V_CC + 5%, V_I = 50 mV;
Typical condition: 25°C; V_CCIO = V_CC, V_I = V_CC – 5%;
Maximum condition: 100°C; V_CCIO = V_CC – 5%, V_I = V_CC – 5%; in which V_I refers to the input voltage at the I/O pin.

Note to Table 1–13:
(1) The I/O ramp rate is 10 ns or more. For ramp rates faster than 10 ns, |IIOPIN| = C dv/dt, in which C is the I/O pin
capacitance and dv/dt is the slew rate.
1 During hot-socketing, the I/O pin capacitance is less than 15 pF and the clock pin
capacitance is less than 20 pF.
