3.3 LED Display
Register 19 is used for different mode led display. There are two kind of led display
mechanisms provided by ADM7008: single and dual color led mode, either mode provide
power on LED self test to minimize and ease the system test cost.
3.3.1 Single Color LED
When Single Color LED is programmed (DUALLED is set to low during power on reset),
all ports LED will be Off during power on reset (Output value same as recommend value
on LED pins). After power on reset, all internal parallel LEDs will be On for 2 seconds,
internal parallel LED status will be streamed out through LED_DATA and this signal is
output by ADM7008 at the falling edge of LED_CLK. Before describing the serial LED
output data format, we tend to describe the meaning of internal parallel LEDs.
There are three types of LED supported by ADM7008 internally. The first is LNKACT,
which represents the status of Link and Transmit/Receive Activity; the second is LDSPD,
which indicates the speed status and the last is DUPCOL, which shows pure duplex status
in full duplex and duplex/collision combined status in half duplex. All these three LED
can be controlled by Register 19 to change display contents.
After LED self test, Table 3-4, 3-5 and 3-6 show the On/Off polarity according to
different recommended value setting for LDSPD, DUPCOL and LNKACT. When the
recommend value is high, ADM7008 will drive LED LOW; ADM7008 will drive the
LED HIGH when the recommend value is low, instead.
