Output-only signals that are always driven; no external pull-up required
Type A output with weak P-channel pull-up during reset
Three-state output that includes circuitry to pull up output before high impedance is
established, to ensure rapid rise time. An external holding resistor is required to maintain
logic level while the pin is in the high-impedance state.
Type B output that can be operated in an open-drain mode
