For two pin Bi-color LED mode (LEDMode[1:0]=10), Bi-color Link/Act (pin LED_ADD) and Spd (pin LED_SPD) can be used
for one Bi-color LED package, which is a single LED package with two LEDs connected in parallel with opposite polarity. When
LEDMode[1:0]=10, the active status of LED_ADD is opposite with LED_SPD, does nothing with input upon reset.
Spd:Input=Floating, Active Low.
Bi-color Link/Act:
the active status of
LED_ADD is opposite with LED_SPD,
does nothing with input upon reset.
