1 See Output Drive Currents on Page 73 for more information about each driver type.
2 HWAIT must be pulled high or low to configure polarity. It is driven as an output and toggle during processor boot. See Booting Modes on Page 18.
3 When driven low, this ball can be used to wake up the processor from the hibernate state, either in normal GPIO mode or in Ethernet mode as MII PHYINT. If the ball is
used for wake up, enable the feature with the PHYWE bit in the VR_CTL register, and pull-up the ball with a resistor.
4 Consult version 2.1 of the I2C specification for the proper resistor value.
