Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

The IXF1104 MAC initiates a current address read by sending a device address with the Read/ Write bit set High. The optical module acknowledges the device address and serially clocks out the data word. The IXF1104 MAC does not respond with a zero but generates a stop condition (see Figure 28).

5.8LED Interface

The IXF1104 MAC uses a Serial interface, consisting of three signals, to provide LED data to some form of external driver. This provides the data for 12 separate direct drive LEDs and allows three LEDs per MAC port.

There are two modes of operation, each with its own separate LED decode mapping. Modes of operation and LEDs are detailed in the following sections.

5.8.1Modes of Operation

There are two modes of operation: Mode 0 and Mode 1. Mode selection is accomplished by using the LED_SEL_MODE bit. This bit is globally selected and controls the operation of all ports (see Table 109 “LED Control ($0x509)” on page 190).

Mode 0: (LED_SEL_MODE = 0 [Default]): This mode selects operations compatible with the SGS Thompson M5450 LED Display Driver device. This device converts the serial data stream, output by the IXF1104 MAC, into 30 direct-drive LED outputs. Although the LED interface is capable of driving all 30 LEDs, only twelve will be driven in the four-port IXF1104 MAC, three LEDs per port.

Mode 1: (LED_SEL_MODE = 1): This mode is used with standard TTL (74LS599) or HCMOS (74HC599) octal shift registers with latches, providing the most general and cost-effective implementation of the serial data stream conversion.

In addition to these physical modes of operation, there are two types of specific LED data decodes available for fiber and copper modes. This option is a global selection and controls the operation of all ports (see Table 109 “LED Control ($0x509)” on page 190).
