Signals with a # suffix are active low.
Signals described in this chapter utilize the following IO cell types:
The following provides definitions and reference data about each of the IC’s pins. “During Reset” provides the
state of the pin while RESET# is asserted. “After Reset” provides the state of the pin immediately after
RESET# is deasserted. “Func.” means that the pin is functional and operating per its defined function.
Name Notes
Input Input signal only.
Output Output signal only. This includes outputs that are capable of being in the high-impedance state.
OD Open drain output. These signals are driven low and expected to be pulled high by external cir-
cuitry.
IO Input or output signal.
IOD Input or open-drain output.
Analog Analog signal.
w/PU With pullup. The signal includes a pullup resistor to the signal’s power plane. The resistor value is
nominally 8K ohms.
