If two-color mode is enabled for pair
LED_LNK/ACT and LED_1000, the signal
output for LED_LNK/ACT is equal to
LED_LNK/ACT and LED_1000. When
LED_LNK/ACT and LED_1000 are not
mutually exclusive (such as duplex and
collision), this mode can simplify the external
circuitry because it ensures either LED_LNK/
ACT and LED_1000 is on, and not both at the
same time. The same rule applies to pair
LED_100 and LED_10.
1b = Two-color mode for LED_100 and
LED_10.
0b = Normal mode for LED_100 and LED_10.
