Version: DM9081-DS-F01
April 22, 1997
Normal Mode
In normal mode, TESTPIN0 and TESTPIN1 must be
pulled high. The COL_LED, AUI1_CRS_LED and
AUI2_CRS_LED pins are defined as minimum mode,
whereas the other LED drive pins require external devices
to display the status from the LED pins. These pins
transmit information from the DM9081 by first sending
Bit 7. A detailed timing diagram is given in Figure 3. The
shift logic and latch device shown in Figure 4 is used to
convert received serial data into byte- oriented data. The
output data is used to drive the LED.
LED Latch
The LED_LATCH pin is used to latch the byte-oriented
data. The rising edge of the TCK clock, occurring on the
high state LED_LATCH, is used to strobe in the state of
the following LED pins.
