INITIALIZATION AND SETUP
HARDWARE CONFIGURATION
Several different states of operation can be chosen through hardware configuration. External pins may be pulled high or low
at reset time. The combination of high and low values determines the power on state of the device.
Many of these pins are multi-function pins which change their meaning when reset ends.
SOFTWARE CONFIGURATION
Several different states of the transceiver operations can be chosen through MDC/MDIO interface. For details, see “Register
Descriptions” on page 19.
LEDS
Using an LED display matrix with a refresh technique, only 14 pins are required to drive up to 48 LEDs with unique
information. On, Off, and Flash states are used to indicate different information. With a reduced number of signals, the LED
display is easier to route on the board, and less costly. The active-low LED data is driven out of LED_D[0:7] pins for each
port and the corresponding LED functions are LED_LN[5:0] pin. For details, see “LED Display/Configuration/PROM
Interface” on page 17 and “LED Display Matrix” on page 37.
The AC206 supports two LEDs per port. The following table describes how each of the LED is connected.
Signals LED_D[2:6] are indicators of port 1 through 5. Signals LED_LN[0:5] are events driven of port 1 through 5.
