Description
High impedance
Pull up, 10 kΩ
Pull down, 10 kΩ
Pull down, 20 kΩ
Tristate capability: The corresponding pin has 3 operational states: Low, high and high-
impedance.
Open Drain. The corresponding pin has 2 operational states, active low and tristate, and
allows multiple devices to share as a wire-OR. An external pull-up is required to sustain the
inactive state until another agent drives it, and must be provided by the central resource.
Open Collector
Push-Pull. The corresponding pin has 2 operational states: Active-low and active-high
(identical to output with no type attribute).
Open-Drain or Push-Pull. The corresponding pin can be configured either as an output with
the OD attribute or as an output with the PP attribute.
