15.2 Signal Description
Table 15-1 on page 552 and Table 15-2 on page 552 list the external signals of the Ethernet Controller
and describe the function of each. The Ethernet LED signals are alternate functions for GPIO signals
and default to be GPIO signals at reset. The column in the table below titled "Pin Assignment" lists
the GPIO pin placement for the LED signals. The AFSEL bit in the GPIO Alternate Function Select
(GPIOAFSEL) register (page 309) should be set to choose the LED function. For more information
on configuring GPIOs, see “General-Purpose Input/Outputs (GPIOs)” on page 287. The remaining
signals (with the word "fixed" in the Pin Mux/Pin Assignment column) have a fixed pin assignment
and function.
